| Abstract: As a functional inorganic material, LiAlO2 was focused on widely, especially in the field of tritium breeder of fusion reactor. In this article, the proper reaction conditions and mechanism to synthesis the γ-LiAlO2 by solid state method are considered. In the experiments, it has been found that the phase of β- and γ-LiAlO2 are only produced by the reaction of LiOH and Al2O3, while the α- and γ-LiAlO2 can be obtained by the reaction of Li2CO3 and Al2O3. As compared with Li2CO3 and Al2O3 reacted at 900～1000℃ for the preparation of γ-LiAlO2, the γ-LiAlO2 can also be made by the reaction of LiOH and Al2O3 at some more lower temperatures that is due to the bulk diffuse mech-anism. But the former can get better crystal and have smaller particles for the mechanism of surface fast reaction. As a result, the sub-micron γ-LiAlO2 powders with the diameter less than 0.3μm are obtained. |
