Unleashing the Power of Silica Sol: A Look into the Leading Manufacturers
Silica sol is a colloidal form of silica that is widely used as a binder, a thickening agent, and a catalyst in various industrial processes. Its unique properties, such as high surface area, stability, and biocompatibility, make it an attractive material for a wide range of applications, including ceramics, catalysts, coatings, and electronics.
Colloidal silica is a stable suspension or dispersion of sub-micron amorphous silica particles in a liquid medium, usually water. The particles are typically spherical and have a size range of 1-100 nanometers in diameter. Colloidal silica has a high surface area and exhibits unique properties such as high stability, high surface activity, and high reactivity due to its small particle size.
Zhejiang Delixin Micro Nano Technology Co., Ltd. is a leading manufacturer and exporter of silica sol in China. The company offers a wide range of silica sol products, including acidic silica sol, alkaline silica sol, and neutral silica sol.
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, sapphire polishing, gallium arsenide, silicon wafer polishing, cement curing agent, refractory materials, etc.
