Mechanochemical synthesis of fine-particle γ-LiAlO2

Abstract

Using thermogravimetry, in situ X-ray diffraction, room-temperature X-ray diffraction, specific surface area measurements, and particle size analysis, we have studied how preliminary mechanical activation of a mixture of aluminum hydroxide and lithium carbonate in an AGO-2 planetary mill and subsequent heat treatment of the mixture influence the synthesis of fine-particle nanostructured gamma-lithium monoaluminate. We have proposed a scheme of the structural changes accompanying the synthesis of gamma-lithium monoaluminate.
