Germanium dioxide, also called germanium oxide and germania, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
VANADIUM PENTOXIDE (1314-62-1)
Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.
Nitrate is a polyatomic ion with the molecular formula NO− 3 and a molecular mass of 62.0049 u. Nitrates also describe the organic functional group RONO2. These nitrate esters are a specialized class of explosives.
