Abstract
Lithium γ–monoaluminate was obtained as a result of mechanochemical activation of the mixture of lithium carbonate and aluminium hydroxide in AGO-2 planetary activator, followed by the thermal treatment. The effect of mixture composition and humidity on the phase composition and specific surface of lithium γ–monoaluminate was studied. It was shown that in the variation of the composition and humidity of the mixture the specific surface area of the final product decreases significantly (from 13 to 0.2 m2/g).
