Crystalline fine powders of LiAlO 2 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‐LiAlO 2 of ∼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.
