Germanium (specifically, germanium (IV ) nitride ) is an inorganic chemical compound of the germanium from the group consisting of the nitrides.
Production and representation
Germanium may be obtained by the reaction of germanium with ammonia at 700 ° C.
2 it can be shown at about 300 ° C by thermal decomposition of germanium (IV), Ge -imide (NH).
Properties
Germanium is, in the pure state, a colorless, extremely inert solid. It does not react with hot mineral acids or alkalis. Hydrogen reduces the connection until at 700 ° C for germanium, chlorine reacts at 600 ° C to germanium ( IV) chloride and nitrogen. Germanium of a plurality of modifications are known, wherein the hexagonal β - form ( phenacite structure) is the most stable. The resulting high-pressure γ - form has a spinel structure.
