砷酸钡

砷酸钡是一种无机化合物，化学式为Ba3(AsO4)2。它可由氧化钡和五氧化二砷加热反应制得。Durif, Andre. Structure cristalline des orthovanadates et orthoarseniates de baryum et de strontium. Acta Crystallographica (1959), 12, 420-421. .它的水合物（16.3H2O及17H2O）也是已知的。Matthias Weil. Insights into Formation Conditions, Crystal Structures, and Thermal Behavior of Hydrous and Anhydrous Barium Arsenates. Cryst. Growth Des. 2016, 16, 2, 908–921. .

它在高温下可以被碳还原，经亚砷酸钡（Ba3(AsO3)2）中间体可以得到砷化钡。Guerin, Henri. Reduction of alkaline earth arsenates by carbon: tribarium arsenate. Compt. rend. (1935), 200, 129-131.
