Mô tả
Lust light green crystalline powder,slightly soluble in water and
oxalic acid,soluble in strong acid,freely soluble in alkali salt solution of
oxalic acid and ammonia water. Aquo compound of 2NiC2O4.NH3.6H2O
or NC2O4.2NH3.5H2O are formed in
the solution of ammonia water. Dehydrate at 150,decompound at 320° in
vacuum;C,at 320-380°, decompound quickly into carbon monoxide, carbon dioxide
and nickle monoxide.
ỨNG DỤNG
Mainly used as nickle
catalyzer, in producing super fine nickel oxide and reducing metal nickle
powder.
