Synthesis of Lithium Orthosilicate by Polymer Precursor Route

摘要

My objective in this project is to synthesize phase pure lithium orthosilicate by using a novel polymer precursor route and simultaneously compare the results with lithium orthosilicate prepared by conventional solid state method. Source of silica is very important for the formation of lithium orthosilicate. For our work, the objective can be broadly highlighted as follows: 1. To study the effect of different sources of silica on the phase formation behaviour of lithium orthosilicate. 2. To compare the properties (thermal and microstructural) of lithium orthosilicate derived from polymer route and conventional solid state route. 3. To study the densification behaviour of polymer derived lithium orthosilicate and solid state synthesized lithium orthosilicate. 4. To study the effect of non-stoichiometric amount of silica on lithium sublimation.
