Silica sol precision casting technology is a more advanced casting technology, the processing of products with high quality and can reach the standard level of castings.

Silica sol as the nanoscale dispersion of silica particles in the water or solvent. Because the SiO2 in silicon sol contains large amounts of water and hydroxyl groups, so the silicasol also can be expressed as SiO2. NH2O. Preparation of silica sol have a different way. The most commonly used method with ion exchange method, silicon powder step hydrolysis method, silane hydrolysis method, etc.

Silica sol is a colloidal solution, odorless, non-toxic. Silica sol as the nanoscale dispersion of silica particles in the water or solvent. Because the SiO2 in silicon sol contains large amounts of water and hydroxyl groups, so the silicasol also can be expressed as SiO2. NH2O.
