Boron: Making Modern Life Possible

When it comes to modern living, there are so many things we take for granted.

We sleep in warm and comfortable houses, while keeping our food fresh and refrigerated. We have screens in our pockets and throughout our homes that help us to connect with our friends and family – and we can drive across town in minutes to see them, if need be.

Oddly enough, many of these subtle aspects of modern living would not be possible without the existence of very specific minerals and the developments in technology that allow them to be used to their full potential.

Enter Boron

Boron is an unlikely hero in this regard.

Today’s infographic comes from 20 Mule Team Borax, and it covers the properties, applications, market, and future trends surrounding boron. And even though you probably didn’t know much about this metalloid element before today, you’ll soon see that boron’s versatile applications make it an integral part of modern life in many ways:

In fact, boron has an incredible range of properties and uses that make it interesting to us humans:

  • It’s an essential micronutrient for plants
  • It improves the performance of cleaning products
  • It captures neutrons, making nuclear reactors safer
  • It absorbs infrared light, useful for energy efficiency
  • Boron limits growth of bacteria and fungi on wood products
  • It helps to balance acidity and alkalinity
  • Boron makes glass resistant to heat or chemicals
  • Boron prevents corrosion in many settings
  • It be used to make advanced materials
  • It can be used in materials and coatings to suppress flames
  • Boron can be added to steel or aluminum, or used in super-magnets
  • It can link alcohols and carbohydrates together in oil recovery

As a result of this vast array of applications, boron is used in everything from smartphone screens to fertilizer.

Small amounts of boron sit in the walls and ceiling of your home, your kitchen, your bathroom, and your driveway – and it’s even in a lot of food since it is an essential micronutrient for plants.

Future Megatrends

There are three megatrends that are driving future boron consumption: urbanization, energy, and agriculture.

Urbanization
By 2025, China will have 221 cities with over 1 million people. Boron is heavily used in cities and buildings, in applications such as glazed ceramics, LCD televisions and electronics, appliances, and textile fiberglass.

Agriculture
Because boron helps regulate the reproductive cycle of plants, it is needed to help maximize food production for a growing population. In India, the use of boron and other micronutrients is being supported by government projects and subsidies to ensure that farmers increase productivity.

Energy
Boron is also used in energy saving applications such as insulation, which will be key as green building practices are encouraged throughout the world. Borates are also used to create the high-powered magnets in applications like wind turbines, making them even more important for a green future.

More Than Precious: Silver’s Role in the New Energy Era (Part 3 of 3)

Long known as a precious metal, silver in solar and EV technologies will redefine its role and importance to a greener economy.

Silver More Than Precious

Silver’s Role in the New Energy Era (Part 3 of 3)

Silver is one of the first metals that humans discovered and used. Its extensive use throughout history has linked its name to its monetary value. However, as we have advanced technologically, so have our uses for silver. In the future, silver will see a surge in demand from solar and electric vehicle (EV) technologies.

Part 1 and Part 2 of the Silver Series showcased its monetary legacy as a safe haven asset as a precious metal and why now is its time to shine.

Part 3 of the Silver Series comes to us from Endeavour Silver, and it outlines silver’s role in the new energy era and how it is more than just a precious metal.

A Sterling Reputation: Silver’s History in Technologies

Silver along with gold, copper, lead and iron, was one of the first metals known to humankind. Archaeologists have uncovered silver coins and objects dating from before 4,000 BC in Greece and Turkey. Since then, governments and jewelers embraced its properties to mint currency and craft jewelry.

This historical association between silver and money is recorded across multiple languages. The word silver itself comes from the Anglo-Saxon language, seolfor, which itself comes from ancient Germanic silabar.

Silver’s chemical symbol, “Ag”, is an abbreviation of the Latin word for silver, argentum. The Latin word originates from argunas, a Sanskrit word which means shining. The French use argent as the word for money and silver. Romans bankers and silver traders carried the name argentarius.

While silver’s monetary meanings still stand today, there have been hints of its use beyond money throughout history. For centuries, many cultures used silver containers and wares to store wine, water, and food to prevent spoilage.

During bouts of bubonic plague in Europe, children of wealthy families sucked on silver spoons to preserve their health, which gave birth to the phrase “born with a silver spoon in your mouth.”

Medieval doctors invented silver nitrate used to treat ulcers and burns, a practice that continues to this day. In the 1900s, silver found further application in healthcare. Doctors used to administer eye drops containing silver to newborns in the United States. During World War I, combat medics, doctors, and nurses would apply silver sutures to cover deep wounds.

Silver’s shimmer also made an important material in photography up until the 1970s. Silver’s reflectivity of light made it popular in mirror and building windows.

Now, a new era is rediscovering silver’s properties for the next generation of technology, making the metal more than precious.

Silver in the New Energy Era: Solar and EVs

Silver’s shimmering qualities foreshadowed its use in renewable technologies. Among all metals, silver has the highest electrical conductivity, making it an ideal metal for use in solar cells and the electronic components of electric vehicles.

Silver in Solar Photovoltaics

Conductive layers of silver paste within the cells of a solar photovoltaic (PV) cell help to conduct the electricity within the cell. When light strikes a PV, the conductors absorb the energy and electrons are set free.

Silver’s conductivity carries and stores the free electrons efficiently, maximizing the energy output of a solar cell. According to one study from the University of Kent, a typical solar panel can contain as much as 20 grams of silver.

As the world adopts solar photovoltaics, silver could see dramatic demand coming from this form of renewable energy.

Silver in Electric Vehicles

Silver’s conductivity and corrosion resistance makes its use in electronics critical, and electric vehicles are no exception. Virtually every electrical connection in a vehicle uses silver.

Silver is a critical material in the automotive sector, which uses over 55 million ounces of the metal annually. Auto manufacturers apply silver to the electrical contacts in powered seats and windows and other automotive electronics to improve conductivity.

A Silver Intensive Future

A green future will require metals and will redefine the role for many of them. Silver is no exception. Long known as a precious metal, silver also has industrial applications metal for an eco-friendly future.

Visualizing China’s Dominance in Rare Earth Metals

Rare earth deposits exist all over the planet, but the majority of the world’s rare earth metals are produced and refined in China.

China’s Dominance in Rare Earth Metals

Did you know that a single iPhone contains eight different rare earth metals?

From smartphones and electric vehicles to x-rays and guided-missiles, several modern technologies wouldn’t be what they are without rare earth metals. Also known as rare earth elements or simply “rare earths”, this group of 17 elements is critical to a number of wide-ranging industries.

Although deposits of rare earth metals exist all over the world, the majority of both mining and refining occurs in China. The above graphic from CSIS China Power Project tracks China’s exports of rare earth metals in 2019, providing a glimpse of the country’s dominating presence in the global supply chain.

China’s Top Rare Earth Export Destinations

Around 88% of China’s 2019 rare earth exports went to just five countries, which are among the world’s technological and economic powerhouses.

Export DestinationShare of China's Rare Earth ExportsTop Rare Earth Import (tons)
Japan36.0%Cerium
United States33.4%Lanthanum
Netherlands9.6%Lanthanum
South Korea5.4%Lanthanum
Italy3.5%Cerium
Rest of the World12.1%Cerium

Japan and the U.S. are by far the largest importers, collectively accounting for more than two-thirds of China’s rare earth metals exports.

Lanthanum, found in hybrid vehicles and smartphones, was China’s largest rare earth export by volume, followed by cerium. In dollar terms, terbium was the most expensive—generating $57.9 million from just 115 metric tons of exports.

Why China’s Dominance Matters

As the world transitions to a cleaner future, the demand for rare earth metals is expected to nearly double by 2030, and countries are in need of a reliable supply chain.

China’s virtual monopoly in rare earth metals not only gives it a strategic upper hand over heavily dependent countries like the U.S.—which imports 80% of its rare earths from China—but also makes the supply chain anything but reliable.

“China will not rule out using rare earth exports as leverage to deal with the [Trade War] situation.”

—Gao Fengping et al., 2019, in a report funded by the Chinese government via Horizon Advisory.

A case in point comes from 2010 when China reduced its rare earth export quotas by 37%, which in part resulted in skyrocketing rare earth prices worldwide.

The resulting supply chain disruption was significant enough to push the EU, the U.S., and Japan to jointly launch a dispute settlement case through the World Trade Organization, which was ruled against China in 2014.

On the brighter side, the increase in prices led to an influx of capital in the rare earth mining industry, financing more than 200 projects outside China. While this exploration boom was short-lived, it was successful in kick-starting production in other parts of the world.

Breaking China’s Rare Earth Monopoly

China’s dominance in rare earths is the result of years of evolving industrial policies since the 1980s, ranging from tax rebates to export restrictions. In order to reduce dependence on China, the U.S. and Japan have made it a priority to diversify their sources of rare earth metals.

For starters, the U.S. has added rare earth metals to its list of critical minerals, and President Donald Trump recently issued an executive order to encourage local production. On the other side of the world, Japan is making efforts to reduce China’s share of its total rare earth imports to less than 50% by 2025.

Increasing rare earth mining outside of China has reduced China’s global share of mining, down from 97.7% in 2010 to 62.9% in 2019. But mining is merely one piece of the puzzle.

Ultimately, the large majority of rare earth refining, 80%, resides in China. Therefore, even rare earths mined overseas are sent to China for final processing. New North American refining facilities are being set up to tackle this, but the challenge lies in managing the environmental impacts of processing rare earths.
