Molecular formula: Typical formula like Al₂(SiO₃)₃
Appearance: Usually appears as a white, fine powder with high uniformity.
Particle Size: Ultrafine aluminum silicate, also known as nano aluminum silicate or fine aluminum silicate, features an extremely small particle size. The particles are often in the nanometer to sub - micrometer range, which endows it with unique properties. This fine particle size provides a large specific surface area, enhancing its reactivity and interaction with other substances.
Color and Whiteness: It has a pure white color and high whiteness, making it an ideal additive in applications where color purity is crucial, such as in paper - grade aluminum silicate, coating - grade aluminum silicate, and in the cosmetics industry.
Density: With a relatively low density, it can be easily dispersed in various matrices without significantly increasing the overall weight. This property is beneficial for applications in plastics, rubber - grade aluminum silicate, and coatings.
Chemical Stability: High purity aluminum silicate exhibits excellent chemical stability. It is resistant to most common chemicals, which allows it to maintain its properties in different environments and during various manufacturing processes.

In Paper Coating: Paper - grade aluminum silicate is an important additive in paper coating. It improves the smoothness, brightness, and ink - receptivity of the paper surface. This results in better - quality printed materials with sharper images and more vivid colors.
In Coatings: Aluminum silicate for coatings is widely used. Its fine particle size helps to improve the smoothness and gloss of coatings. It can also enhance the adhesion of the coating to the substrate, increase the durability and weather resistance of the coating. In paints, aluminum silicate in paints acts as a functional filler, reducing the cost while maintaining or even improving the performance of the paint.
In Painting: Ultra-fine silica alumina can replace part of titanium dioxide pigments. Its dry film covering power will not change, and it can improve the whiteness of the paint. If the amount of titanium dioxide pigment remains unchanged, its dry film covering power will significantly increase, and the whiteness will be greatly improved.
The pH value range of ultra-fine silica alumina is 9.7 - 10.8. It has a pH buffering effect. Especially during the storage of vinyl acetate emulsion paint, it can prevent the phenomenon of pH value drop due to vinyl acetate hydrolysis, increase the dispersion stability of the latex paint, and avoid the corrosion of the inner wall of metal containers.
The ultra-fine structure and grid structure of silica alumina make the latex paint system slightly thicker, have good suspension properties, and prevent the sedimentation of solid parts and the occurrence of surface water separation.
Ultra-fine silica alumina makes the latex paint film have good scrub resistance, weather resistance, and can shorten the surface drying time.
Ultra-fine silica alumina has a blurring effect, so it can be used as an economical blurring agent in semi-gloss and matte paints, but not suitable for gloss paints.
In Cosmetics: Aluminum silicate in cosmetics is used in various products such as powders, f oundations, and blushes. Its high whiteness and fine texture contribute to a smooth and natural finish. It can also help to absorb excess oil on the skin, making it a popular ingredient in oil - control products.
In Ceramics: Aluminum silicate ceramics are known for their high mechanical strength, good thermal stability, and low thermal expansion coefficient. Ultrafine aluminum silicate is used as a key raw material in the production of advanced ceramics, which are applied in high - temperature environments, such as in the aerospace and electronics industries.
In Rubber: Rubber - grade aluminum silicate is added to rubber compounds. It can improve the mechanical properties of rubber, such as tensile strength, tear resistance, and abrasion resistance. Aluminum silicate in rubber also helps to reduce the viscosity of the rubber compound during processing, making it easier to shape and mold.
In Plastics: Aluminum silicate in plastics is used as a filler. It can enhance the stiffness, dimensional stability, and heat resistance of plastics. By adding ultrafine aluminum silicate, the plastic products can have better performance while keeping the cost down.
