Abstract

Abstract: Anew method for preparing V₂O₃ by decomposing hydrazine-eontaining vanadium salt thermally was described.The hydrazine-containing vanadium salt is synthesized by the reaction between ammonium metavanadate and hydrazine in an oxalic acid medium, and under an atmosphere of nitrogen V₂O₃ can be prepared from the hydrazine-containing vanadium salt by the thermal decomposition.It shows that V₂O₃ has magnetism and electrical conductivity.

Key words: Hydrazine, Vanadium trioxide, Thermal decomposition
