Synthesis of LiAlO2 Powder by Hydrolysis of Metal Alkoxides

Abstract

Crystalline fine powders of LiAlO2 can be prepared by hydrolysis of metal alkoxides for application to the breeder blanket in nuclear fusion. The precipitates were fine crystalline particles of β‐LiAlO2of ∼0.1‐μm size under controlled conditions. The transformation from β‐ to γ‐phase was confirmed at temperatures between 700° and 750°C. The microstructure of a sintered body at 1000°C consisted of homogeneous fine particles and pores suitable for the blanket material. A fully dense sintered body could be prepared at 1400°C.
