Colloidal Silica/Silica Sol With Small Particle Size

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.

More Information About Colloidal Silica/Silica Sol With Small Particle Size

Colloidal silica, also known as silica sol, is a stable dispersion of sub-micron silica particles in a liquid, typically water. It is widely used in various applications such as coatings, adhesives, and ceramics, due to its unique properties such as high surface area, high purity, and uniform particle size distribution.
Colloidal silica with small particle size is particularly useful in many applications because it has a larger surface area per unit volume than larger particles. This increased surface area can lead to improved performance in areas such as catalysis, adsorption, and mechanical strength.
The particle size of colloidal silica is typically measured in nanometers (nm), with smaller particle sizes ranging from 5-50 nm. In addition to the particle size, the stability and uniformity of the dispersion are also important factors to consider for applications where consistency and reliability are critical.
Colloidal silica can be synthesized using various methods, including Stöber synthesis, sol-gel process, and precipitation methods. The choice of method can affect the particle size and properties of the resulting colloidal silica, making it important to select the appropriate synthesis method based on the intended application.

Here are some common uses of colloidal silica with small particle size:

As a binder: Colloidal silica can be used as a binder in a variety of applications, including coatings, adhesives, and composites. Its small particle size and high surface area make it an excellent bonding agent, improving the strength and durability of the finished product.
In polishing and abrasives: The small particle size and high hardness of colloidal silica make it ideal for use in polishing and abrasive applications. It is commonly used in the manufacture of dental and optical products, as well as in the semiconductor and electronics industries.
As a catalyst support: Colloidal silica can be used as a support for catalysts in a variety of chemical reactions. Its high surface area and small particle size make it an effective carrier for catalysts, improving the efficiency and selectivity of the reaction.
In coatings and paints: Colloidal silica can be added to coatings and paints to improve their hardness, durability, and scratch resistance. It can also be used to create matte finishes and to reduce the amount of organic solvents required in the formulation.
In chromatography: Colloidal silica is often used as a stationary phase in chromatography, a technique used to separate and analyze complex mixtures. Its small particle size and high surface area make it an effective adsorbent for a wide range of molecules.
Overall, colloidal silica with small particle size is a versatile material with a wide range of applications in various industries. Its unique properties make it an effective additive for improving the performance and functionality of many products.
