Abstract
Low-temperature (<500°C) stages in the synthesis of gamma-lithium monoaluminate through heat treatment of a mechanically activated mixture of aluminum hydroxide and lithium carbonate have been studied by thermogravimetry and differential scanning calorimetry in combination with mass spectrometry. The results demonstrate that heating the mixture to above 80–100°C is accompanied by the release of not only water (resulting from the decomposition of X-ray amorphous aluminum hydroxide) but also carbon dioxide. The carbon dioxide originates from the reaction of the lithium carbonate with the products of X-ray amorphous aluminum hydroxide thermolysis.
