摘要：

Extraction of lithium by vacuum thermal reduction may be used extensively in future. Influences of various technological parameters such as reaction temperature and time on thermal decomposition of lithium carbonate and Lithia reduction were investigated in the of extraction of lithium by vacuum thermal reduction with Ferro-silicon alloy. On the best condition obtained by L-9(4(3)) orthogonal test, the decomposition efficiency of lithium carbonate could be above 99%. With increasing reduction temperature, the reduction rate could be reach up to 95.85% at 1293K. The reduction rate increased gently when the reaction time excess 120min.
