砷化钡

砷化钡是一种无机化合物，化学式为Ba3As2。它可由碳在高温还原砷酸钡制得。Guerin, Henri. Reduction of alkaline earth arsenates by carbon: tribarium arsenate. Compt. rend. (1935), 200, 129-131.
 Ba3(AsO4)2 + 8 C → Ba3As2 + 8 CO

反应
砷化钡和金反应，可以得到砷化亚金钡和二金化钡：Jürgen Nuss, Martin Jansen. BaAuP and BaAuAs, Synthesis via Disproportionation of Gold upon Interaction with Pnictides as Bases. Z. Anorg. Allg. Chem. 2009. 635. 1514-1516. .

 Ba3As2 + 4 Au → 2 BaAuAs + BaAu2
