Silica Sol
Silica sol is a kind of milky colloid, which is a kind of colloidal solution formed by the dispersion of micro silicon oxide colloidal particles with a diameter of 10-20nm into the water. It is mainly used in the refractory material industry, coating industry, papermaking industry and precision casting, and can also used as catalyst material or carrier.
