Preparation of Lithium Orthosilicate Ceramic Pebbles by Molten Spray Method Process

Article Preview

Abstract:

Lithium orthosilicate (Li4SiO4) ceramic pebbles was prepared by molten spray process, using lithium carbonate (Li2CO3) and silica (SiO2) as raw material. The XRD experimental investigation results showed that the main crystal phase of the ceramic pebbles is Li4SiO4 with small amount of impurity phase, Li2SiO3, and some unreacted SiO2. The average pebbles size is 0.22mm. The sphericity of the pebble is 99%.
