Product Description

Product Description

Aluminium silicate powder has its origin deeply rooted in natural minerals and industrial processes.
In nature,over long geological time - scales, chemical reactions in the Earth's crust break down the original rock structures. Silicon oxygen tetrahedra and aluminium - oxygen polyhedra recombine, resulting in the formation of kaolinite and other aluminium - silicate minerals. These natural minerals can be mined and processed to obtain aluminium silicate powder. The mining process involves extracting the ore from deposits, followed by crushing, grinding, and beneficiation techniques to separate and purify the aluminium  silicate  bearing components.
Industrially, aluminium silicate powder can also be synthesized. One common method is through chemical reactions. For instance, aluminium salts (like aluminium sulfate) and silicate sources (such as sodium silicate) can be mixed in an aqueous solution under specific pH and temperature conditions. A precipitation reaction occurs, where aluminium and silicate ions combine to form amorphous or crystalline aluminium silicate precipitates. After filtration, washing, and drying, aluminium silicate powder is obtained. This synthetic approach allows for precise control over the powder's composition, particle size, and other properties, meeting the diverse requirements of various industries.

Application

1. Refractory materials: It is widely used in the production of refractory bricks, crucibles, and furnace linings. Its high  temperature resistance and good thermal stability can withstand the harsh high - temperature environment in industrial furnaces, ensuring the normal operation of the equipment.
2. Insulation materials: Aluminium silicate powder is an important raw material for manufacturing insulation boards, insulation cotton, and other insulation materials. It has excellent thermal insulation performance, which can effectively reduce heat transfer and energy consumption, and is widely used in the construction and industrial fields.
3. Paint and coating: As a filler in paints and coatings, it can improve the mechanical properties, weather resistance, and corrosion resistance of the coating film. At the same time, it can also adjust the gloss and viscosity of the paint to make the coating have better application performance.
4. Plastic and rubber: Adding aluminium silicate powder to plastics and rubbers can enhance their strength, hardness, and wear resistance. It can also improve the dimensional stability and heat resistance of plastics and rubbers, expanding their application range.
5. Paper - making industry: In the paper - making process, aluminium silicate powder can be used as a filler and coating pigment. It can improve the whiteness, smoothness, and printing performance of paper, and at the same time reduce the cost of paper production.
