Alternatives Sought for Rare-Earth Materials

Facebook X LinkedIn Email
BERLIN, Oct. 14, 2011 — In response to the shortage of rare-earth metals used for polishing in the optics industry, high-tech industry association Spectaris has developed a “Rare Earth” industrial consortium project to seek out possible alternatives. Export restrictions by key suppliers in China, as well as an increased demand by the electronics industry, have made it difficult to purchase the expensive and dwindling supply of cerium oxide. To overcome this obstacle, the industry consortium, which was launched in December 2010, has begun testing alternative substance polishing agents such as...Read full article
