Purity: 99.9%
It includes M3[NbO(C2O4)3], M[NbO(C2O4)2], M[NBO2C2O4] series complex, where M is potassium, sodium, rubidium and ammonium. Crystal of the first complex can also be obtained, such as K3[NbO(C2O4)3], Na3[NbO(C2O4)3], NH4]3[NbO(C2O4) 4], etc. These crystals have high solubility, at 20 ℃ respectively dissolved 10 g per 100 g water, 8 g, 10 g; When 50 ℃ dissolve 20 g respectively, 56 g, 60 g. (NH4) 3 nbo (C2O4) 3] · 4 h2o crystals are heated to 100 ℃ dehydration, 180 ℃ deamination, 250 ℃ when completely decomposed to generate niobium pentoxide. Niobium oxalate can be prepared from niobium oxalate by fresh niobium hydroxide, oxalic acid and alkali metal salt. It is mainly used in the separation and analytical chemistry of niobium metallurgy.
