Yttrium(III) antimonide

Yttrium(III) antimonide (YSb) is an inorganic chemical compound.

Yttrium antimonide is an intermetallic compound with the chemical formula YSb. It has a NaCl-type structure and is stable in the air. Its thermal expansion coefficient (α, 10−6/°) is 11.1.

It can be produced by the high-temperature reaction of sodium antimonide and anhydrous yttrium chloride:


 * YCl3 + Na3Sb -> YSb + 3 NaCl
