How about Potassium Type Series Colloidal Silica/Silica Sol?

Potassium Type Series Colloidal Silica/Silica Sol is a type of colloidal silica that is stabilized with potassium ions. It is a liquid solution that is composed of silica particles suspended in a liquid medium, typically water. It is used in a wide range of industrial applications, such as coatings, ceramics, electronics, and construction materials. It is also used as a thickening agent, a bonding agent, and a reinforcing filler in various products. The particle size and concentration of the silica particles in the solution can be adjusted to suit the specific application.
