What is Colloidal Silica/Silica Sol With Small Particle Size
Colloidal silica, also known as silica sol, is a stable dispersion of submicron-sized silica particles in a liquid medium. It has a high surface area and is commonly used in various applications, including as a binder, adhesive, and polishing agent. The small particle size of colloidal silica allows for a high degree of surface coverage and enhances its effectiveness in these applications.
Colloidal silica/Silica sol is a kind of colloid which is formed by nm-grade particles SiO2, dispersed in water. It is odorless, tasteless and nontoxic and its chemical molecular formula is mSiO2·nH2O.
1. The colloid particles are minute, and the particle size can be controlled according to customers' requirements.
2. Colloidal silica/Silica sol has relatively large specific surface area, and high heat-resisting performance (1500-1600"C).
3. With low viscosity, it can soak the places where water soaks; therefore, it presents excellent dispersion and permeability.
4. When the moisture contained in silica sol is evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.
Product application: electronics chemicals, paper chemicals, ceramics, cement curing agent, refractory materials, etc.
