characteristics and applications of Colloidal Silica/Silica Sol with Large Particle Size
Colloidal Solution Composition: Composed of nm-grade silicon dioxide (SiO2) particles dispersed in water, forming a stable colloid. It is odorless, tasteless, and nontoxic, with a chemical molecular formula represented as mSiO2·nH2O. Particle Size Control: The particle size of the colloidal silica can be adjusted or controlled according to customers' requirements, offering versatility in various applications. Specific Surface Area and Heat Resistance: Colloidal silica with large particle size exhibits a relatively large specific surface area and high heat-resisting performance, withstanding temperatures ranging from 1500 to 1600°C. This makes it suitable for applications requiring thermal stability and resistance to high temperatures. Low Viscosity and Excellent Dispersion: The colloidal silica has low viscosity, allowing it to penetrate and soak into porous materials effectively. This results in excellent dispersion and permeability, making it suitable for applications where thorough coverage and penetration are desired. Adhesive Properties: When the moisture contained in the silica sol evaporates, the colloid grains firmly adhere to the material surface, forming a strong bond. The combination of silicon and oxygen between grains acts as a good adhesive, enhancing bonding strength. Applications: The product finds application in various industries, including: Ceramics: Used as a binder or additive in ceramic manufacturing processes. Sapphire Polishing: Utilized in the polishing of sapphire substrates for electronics and optics applications. Gallium Arsenide and Silicon Wafer Polishing: Employed in semiconductor manufacturing for polishing substrates. Cement Curing Agent: Used to accelerate the curing process and improve the strength of cementitious materials. Refractory Materials: Used as a binder or additive in the production of refractory materials for high-temperature applications. Overall, Colloidal Silica/Silica Sol with Large Particle Size offers a range of properties suitable for diverse industrial applications, including its use in ceramics, electronics, construction, and materials manufacturing.
