Germanium Metal/ Sputtering Target

Germanium Metal/ Sputtering Target

CAS #: 7440-56-4
Linear Formula: Ge
EC No.: 231-164-3

Product Details

Germanium Metal  is chemically stable and does not react with air or water vapor at normal temperature, but it generates GeO2 very quickly at 600-700 °C. Does not work with hydrochloric acid or dilute sulfuric acid. When concentrated sulfuric acid is heated, helium will dissolve slowly. In nitric acid and aqua regia, it is easily dissolved. The action of the alkaline solution and hydrazine is weak, but the molten alkali is in the air and can dissolve the hydrazine quickly. Germanium and carbon do not work, so they melt in the graphite crucible and are not contaminated by carbon.
