No, potassium silicate and silica are not the same. Potassium silicate is a compound that consists of potassium ions (K+) and silicate ions (SiO4^4-), while silica is a compound made up of silicon and oxygen atoms (SiO2). They have different chemical and physical properties. Potassium silicate is a liquid, while silica is a solid. Potassium silicate is used in a variety of industrial applications, such as in the manufacturing of glass and ceramics, while silica is used in many different industries including construction, electronics, and chemical production.
Ammoniacal Colloidal silica/silica sol is a low density, colloidal silica used as a filler in coating applications. It has negative surface charge and is stabilized with ammonium hydroxide. It has low sodium level, an overall negative particle charge, good binding strength and stability in most applications.
Product application: catalyst support, high gloss photo paper.
