It imposed controls over exports of germanium and gallium products last August. Spot prices of germanium ingot have jumped nearly a third in the past month to an all-time high of 13,250 yuan ...
Silver has numerous nuclear isomers, the most stable being 108m Ag (t 1/2 = 418 years), 110m Ag (t 1/2 = 249.79 days) and 106m Ag (t 1/2 = 8.28 days). All of the remaining radioactive isotopes have half-lives of less than an hour, and the majority of these have half-lives of less than three minutes.

From 1950 through the early 1970s, this area provided an increasing market for germanium, but then high-purity silicon began replacing germanium in transistors, diodes, and rectifiers. [32] For example, the company that became Fairchild Semiconductor was founded in 1957 with the express purpose of producing silicon transistors.
