产品介绍
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.
