砷化镝

砷化镝是一种无机化合物，化学式为DyAs。它可由砷化钠和三氯化镝在高温下反应制得。Fitzmaurice, Jonathan C.; Parkin, Ivan P.; Rowley, Adrian T. Metathesis routes to lanthanide pnictides. Journal of Materials Chemistry (1994), 4(2), 285-289. .它可以形成立方晶系Fmm空间群的晶体，加压至44 GPa时，它会发生相变，转化为P4/mmm空间群的晶体。Shirotani, Ichimin; Yamanashi, Keigo; Hayashi, Junichi; Tanaka, Yuu; Ishimatsu, Naoki; Shimomura, Osamu; Kikegawa, Takumi.
