According...
From the advancements of technology during the Bronze Age to the computers and telecommunication systems of today's Big Data Era, tin has been critical to human progress for at least 5,500 years. Sometime around 3500 BC, Sumerians living in modern day Turkey and Iran discovered that mixing a little tin with copper created bronze, an alloy that produced much more durable weapons and tools than those cast from copper alone. This cutting-edge discovery offered a strategic and...
Considering the almost unfathomable quantities that will be needed to power the global shift to low-carbon energy and electric mobility, copper is the most critical of the minerals and metals that have not been deemed critical by the United States or the European Union. How much demand will it take to push an abundant and widely produced metal like copper to the level of criticality? A doubling of current demand would likely be sufficient, and many analysts are forecasting...
The envisioned green future where every North American is driving a battery-powered electric vehicle charged with renewable energy could be undermined by cobalt, a somewhat scarce and controversial metal that makes lithium-ion batteries better. "Cobalt is considered the highest material supply chain risk for electric vehicles in the short and medium term," the U.S. Department of Energy penned in an April report. This risk has automakers, lithium-ion battery manufacturers, and...
Though it is tough to distinguish the nearly identical properties of niobium and tantalum in nature, at the workplace, one of these critical twin metals typically dons a hardhat and boots to work in the construction and energy industries while you are more apt to find the other working in the high-tech sector. Their differences, however, are subtle, and their careers sometimes overlap. "The leading use of niobium is in the production of high-strength steel alloys used in pipel...
Scandium is an adopted brother to the family of 15 lanthanides that make up the suite of elements known as rare earths. While it may not have quite as strong a chemical bond to its adopted lanthanide siblings as they do to each other, scandium does possess similar characteristics and is almost always found at the same geological gatherings (deposits) as the rest of its rare earth family. Beyond its close chemical and geological ties to rare earths, scandium is considered a...
From the transistors in quantum computers that are millions of times faster than their classical counterparts to fiber optic cables that send data at the speed of light, germanium is a little-known semiconductor that is a small but extremely important ingredient in the technologies behind the future of ultrafast computing and communications. Germanium traces its technological roots back to the 1950s, when scientists developed the transistor to replace vacuum tubes in the...
Lightweight, strong, and resistant to corrosion, titanium is best known for the properties it lends to rockets, aircraft, and high-performance sports equipment. Only about 3% of the more than 8 million metric tons of titanium minerals mined each year globally, however, go into high strength-to-weight ratio and corrosion-resistant alloys. What does drive the mass majority of the demand for this critical mineral is "enwhitening." According to the United States Geological...
Overshadowed by headline-grabbing rare earth elements, gallium is an underappreciated critical metal that is a vital ingredient in next-generation smartphones and communication networks, light-emitting diodes (LEDs), thin-film solar cells, and medical devices. "The development of gallium arsenide as a direct band-gap semiconductor in the 1960s led to what are now some of the most well-known uses of gallium – in feature-rich, application-intensive, third- and f...
Amongst the rarest of the stable elements on the periodic table and an important ingredient in the emerging thin-film solar panel sector, tellurium embodies what it means to be a critical metalloid – an element that possesses the properties of both a metal and non-metal. "Most rocks contain an average of about 3 parts per billion tellurium, making it rarer than the rare earth elements and eight times less abundant than gold," the United States Geological Survey wrote in a 2...
The ability to type, tap, swipe, and scroll your way through articles such as this one from a smartphone, tablet, computer, and now even refrigerators is made possible by indium-tin oxide, which is used as a transparent conducting film applied to virtually every flat-panel display and touchscreen on the market.
