New periodic table shows risks of scarce elements for electronics

By Nick Flaherty www.flaherty.co.uk


Chemists at the University of St Andrews in Scotland have developed a new version of the periodic table which highlights the scarcity of elements used in electronic devices and batteries.

The European Chemical Society (EuChemS) worked with researchers at St Andrews to highlight the remaining availability of all 90 elements and their vulnerabilities, including sourcing from areas of conflict.

The availability of around 15 elements is a challenge because of limited supplies, their location in conflict areas, or the current inability to fully recycle them. The table highlights threats to the supply of gallium, arsenic zinc and even silver, as well as the rising problems for the supply of cobalt, lithium and platinum.

“It is astonishing that everything in the world is made from just 90 building blocks, the 90 naturally occurring chemical elements. There is a finite amount of each and we are using some so fast that they will be dissipated around the world in less than 100 years," said Professor David Cole-Hamilton, emeritus professor of chemistry at St Andrews.

2019 is the United Nations International Year of the Periodic Table (IYPT2019) and the 150th anniversary of scientist Dmitri Mendeleev’s description of the periodic system.
