Silica sol is a stable system of colloidal size amorphous silica particles in water. Due to its large specific surface area, good permeability, adsorption and adhesion, high fire resistance and insulation, silica sol is widely used in textile, paper making, iron and steel casting, metal surface treatment, ceramics, coatings, pigments, etc Adhesives and other industries have been widely used in improving the quality of industrial products, simplifying the production process and saving raw materials.

At present, there are three methods to prepare silica sol in China: ion exchange method, acid neutralization method, electrodialysis method, silica powder dissolution method and colloidal dissolution method. Ion exchange method is mostly used in China, but it has many processes and consumes a lot of energy; In the process of electrolytic electrodialysis, the adsorption and deposition of silica on the anode occur, the voltage and power consumption are relatively high, and the silica sol is easy to polymerize; The acid neutralization method has poor stability, while the colloidal solution method requires higher conditions.

The process of preparing silica sol with metal silicon powder is simple, the cost is low, and the product quality is good, which is more suitable for small and medium-sized enterprises.

The experimental results show that the more the amount of metal silicon powder, the higher the content of SiO2 in the silica sol, and the better the quality of the silica sol. However, adding too much metal silicon powder will bring some difficulties to the vacuum filtration and recycling of metal silicon powder. Considering the economic reasons, the appropriate amount of metal silicon powder should be 160 phr.
