A thermoanalytical study of the solid state reactions in Li_2CO_3-Me_xO_y systems

摘要

The results of a study of the kinetics of the reaction between lithium carbonate and the oxides of some transition metals (Cr, Mo, W) are presented in this work. The reactions were carried out under non-isothermal conditions, in an air atmosphere. The transformation degree, α, was surveyed by thermogravimetic analysis. It was estab- lished by analysis of the experimental data that the reaction between lithium carbonate and chromium (Ⅲ) oxide occurs in one stage, and that the reactions of molybdenum and wolfram oxides with lithium carbonate are more complex.
