Description and Uses

Yttrium oxide was used in the preparation of pervoskite type structure, YAlO₃, containing chrome ions.1 The effect of yttrium oxide dopant on the phase formation and sintering characteristics was studied. It may be used in the manufacturing of neodymium Nd:YAG lasers and in components of MOS and LED transistors.
