At least one metal selected from Group 10 is deposited on the medium pore zeolite and, optionally on the germanium aluminophosphate (AIPO) or a germanium silicoaluminophosphate (SAPO). 2. For FREE! Let's start with its Lewis structure. For example, germanium chloride and germane (GeH4) are a liquid and gas, respectively, that can be very irritating to the eyes, skin, lungs, and throat. [57][58][59] Some zinc-copper-lead ore bodies contain enough germanium to justify extraction from the final ore concentrate. [23] Before 1945, only a few hundred kilograms of germanium were produced in smelters each year, but by the end of the 1950s, the annual worldwide production had reached 40 metric tons (44 short tons).
