Methods of Synthesis of Y₃AI₅O₁₂ (YAG)—A Review

Abstract

Y₂O₃ and AI₂O₃ form three distinct phases of which YAG of empirical formula Y₃AI₅O₁₂ is the most important as an industrial material. There are many different methods of synthesizing the material and extensive literature is available in the form of published documents such as paper and patents related to this. In the present article, an alternative is made to summarize different methods of synthesis of the material YAG as described in such documents. Relevant discussion is also included with respect to crystal structure of different phases and phase diagram in Y₂O₃- AI₂O₃ system.
