Preparation of Finely Crystalline Yttrium-Aluminum Garnet in Solar Furnaces

Аннотация

The possibility is considered of preparing finely crystalline yttrium-aluminum garnet using high-temperature processes in solar furnaces. The effect of concentrated radiation heat flow density during treatment of a mixture of yttrium and aluminum oxides on phase composition of the melt obtained is revealed. The optimum radiation flux density for preparing specimens of finely crystalline single-phase yttrium-aluminum garnet is 8.4 MW/m².
