Yttrium(III) arsenide explained

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.^[1] Some literature has done research on the eutectic system of it and zinc arsenide.^[2]

It reacts with iron, iron(III) arsenide, iron(III) oxide and yttrium(III) fluoride (for doping) at high temperature to obtain superconducting material YFeAsO_0.9F_0.1 (T_c=10.2 K).^[3]
