黄棕色或砖红色粉末，微溶于水，易溶于碱，溶于热浓酸中。700-1125℃时分解失氧。1g溶于约125ml水，溶于碱生成钒酸盐。其酸性溶液能被二氧化硫或锌加盐酸所还原。不溶于乙醇。剧毒，半数致死量（大鼠，经口）10mg/kg。有刺激性。 催化剂，植物接种，阻止紫外线透过玻璃、显影剂、制造黄色玻璃和苯胺黑。二氧化硫氧化为三氧化硫和乙醇氧化为乙醛时的催化剂。 Selective ammoxidation catalysts for such reactions as conversion of toluene to benzonitrile or propylene to acrylonitrile were prepared by a sol-gel method from V2O5, Sb2O3 and high purity hydrogen peroxide. Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, fromV2O5, Bi2O3 and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.
