Yttrium arsenide is an inorganic compound of yttrium and arsenic with the chemical formula YAs. It can be prepared by reacting yttrium and arsenic at high temperature. [2] Some literature has done research on the eutectic system of it and zinc arsenide. [3]
It reacts with iron, iron(III) arsenide, iron(III) oxide and yttrium(III) fluoride (for doping) at high temperature to obtain superconducting material YFeAsO0.9F0.1 (Tc=10.2 K). [4]
