A low pressure process for the production of beta-lithium aluminate (LiAlO2) in a two thermal stage reaction of alumina with liquid phase lithium carbonate comprising admixing powdered alumina with a carbonates composition selected from the group consisting of a ternary lithium-potassium-sodium carbonates composition, a binary lithium-potassium carbonates composition and a binary lithium-sodium carbonates composition, heating the admixture at about 480 DEG to 550 DEG C. in a first thermal stage for a period of time to react the alumina with lithium carbonate to form lithium aluminate, and raising the temperature of the lithium aluminate to about 600 DEG to 650 DEG C. in a second thermal stage for a period of time to transform the lithium aluminate (LiAlO2) to the desired beta-lithium aluminate. |
