Strontium selenide is an inorganic compound with the chemical formula SrSe.
Preparation
Strontium selenide can be prepared by reducing strontium selenate with hydrogen at 600 °C.[1] It can also be produced by reacting strontium and hydrogen selenide in liquid ammonia.[2]
Properties
Strontium selenide crystallizes in the orthorhombic crystal system with space group Fm3m. It has a NaCl structure.[3][4] It transforms into a CsCl structure with a space group Pm3m under high pressure (14 GPa).[5]
It reacts with mercury selenide and germanium diselenide at high temperature to obtain the SrHgGeSe4 crystal.[6] It reacts with thorium and selenium at high temperature in the presence of tin to obtain SrTh2Se5.[7]
