Abstract: 8.7×10<SUP>3</SUP> t/a sodium fluosilicate production process of Red Phosphorus Branch of Yunnan Yuntianhua International Chemical Co.,Ltd.was introduced.With analysis to the factors,such as raw materials and process controllings that can affect quality and consumption of sodium fluosilicate products,following conclusions were obtained:1) concentration of brine and fluorosilicic acid,impurity content and washing water amount are the factors which directly affect quality of sodium fluosilicate products;2) synthesis reaction time and ratio of salt to acid are the key factors affecting consumption of sodium fluosilicate;3) moisture content after dehydration and drying temperature are the critical control points which can affect product′s quality.In order to improve sodium fluosilicate product′s quality and reduce consumption,corresponding control measures，and transformation solutions in response to above factors were put forward.
