Silica sol had has been widely used in the industries of coating,chemical mechanical polishing,precision casting due to the excellent performance of large specific surface area and high stability. With the development of the industry,the filed of application is more wide. Big particle size, high stability,a single dispersed of the sol has been a large number of research. The sol of metal modification,the organic group modification has special performance to adapt to different demand.
