Technology-critical element
A technology-critical element (TCE) is a chemical element that is a critical raw material for modern and emerging technologies, resulting in a striking increase in their usage. Similar terms include critical elements, critical materials, energy-critical elements and elements of security.
Many advanced engineering applications, such as clean-energy production, communications and computing, use emergent technologies that utilize numerous chemical elements. In 2013, the U.S. Department of Energy (DOE) created the Critical Materials Institute to address the issue. In 2015, the European COST Action TD1407 created a network of scientists working and interested on TCEs, from an environmental perspective to potential human health threats.
A study estimated losses of 61 metals to help the development of circular economy strategies, showing that usespans of, often scarce, tech-critical metals are short.
The set of elements usually considered as TCEs vary depending on the source, but they usually include:
Seventeen rare-earth elements
The six platinum-group elements
Twelve assorted elements
Elements such as oxygen, silicon, and aluminum (among others) are also vital for electronics, but are not included in these lists due to their widespread abundance.
