Preparation technology of sodium silicate by water heated alkali reaction and with Panzhihua diatomite was studied by calcination, alkali solution, filtration, and crystallization. The effect of sodium silicate modulus four single factors was the liquid solid ratio ( ratio of distilled water and diatomite) reaction, time and were investigated calcinations temperature and amount of NaOH through the research. It was found that the liquid-solid ratio was 3:1 , the reaction time was 60 min, the amount of NaOH was 12 g and the reaction temperature was 700 ℃, which can be prepared by the modulus of sodium silicate 1. 341 through comprehensive experiments.
