In 1886, chemist Clemens Winkler identified a new element in an unusual mineral from a mine in Saxony and named it in honor of his recently constituted country. Germanium is now a core part of semiconductors used in radio frequency applications such as radar, as well as for fiber optics, solar cells for space flight, and night-vision systems. Key Reading: US, Europe Are Growing Alarmed by China's Rush Into Legacy Chips Pentagon Seeks Supply of Chip Mineral After China Curbs Exports What Are Gallium and Germanium? Niche Metals Hit by China Curbs Xi's Metal Curbs Risk Backfiring as G-7 Seeks Alternatives China accounted for 83% of world production last year, and as of today, exports of germanium and an associated element, gallium, are subject to export controls by Beijing. The curbs on two minor metals that are nevertheless vital to specialized chip production are a result of the great power competition between the US and China that's rippling around the world. China announced the controls on national security grounds, the same justification US President Joe Biden's administration has used for increasingly aggressive measures to deny Beijing access to advanced chip technology. There may be more to come. US and European officials are now growing concerned about China's push into older-generation semiconductors that still dominate the global economy, and are debating new strategies to contain that expansion, Jenny Leonard, Ian King and Alberto Nardelli report. The effect of these tit-for-tat measures is to drive the world's two biggest economies further apart: The US is already seeking alternative supplies of gallium. Japan said it's considering recycling and diversifying its supply of germanium and gallium, which are primarily byproducts of zinc and aluminum production respectively. In June, Swedish miner Boliden said operations at its Tara zinc mine in Ireland — Europe's largest — were ceasing temporarily while it worked on "ensuring its competitiveness." For Europe, it seems, the gravity of the US-China standoff has yet to sink in.— Alan Crawford |
