Description of Crystalline Silica Powder Crystalline Quartz Powder SiO2  :  

Crystalline silica is a kind of inorganic crystal formed by the covalent bond between silicon and oxygen atoms. The compound is unique in its physical and chemical characteristics that allow it to be used in numerous applications across a variety of areas.

The crystal structure of crystalline silica is composed of silicon atoms and oxygen atoms to form a tetrahedral structure by covalent bonding, and these tetrahedral structures are connected by sharing oxygen atoms to form a three-dimensional grid structure. This structure makes the silica have high hardness and high melting point and has excellent thermal and chemical stability.

The physical properties of crystalline silica are also very unique. It has excellent light transmission and can be used to manufacture optical components and window materials. In addition, silica has high insulation and low conductivity, which can be used to manufacture electronic devices and integrated circuits.

Crystalline silica is chemically very stable and insoluble in water and acid and base solutions. It has high corrosion resistance, so it can be used to make products such as glass and ceramics. In addition, silica can also be used as a catalyst and carrier in many chemical reactions.

Crystalline silica is widely used in industry. It can be used as an abrasive and polishing agent for grinding and polishing of various materials. In addition, silica can also be used as an additive in coatings and adhesives, improving their wear resistance and weather resistance. It can also be used as a raw material for glass and ceramic products to prepare high-purity silicate raw materials.

Production Method of Crystalline Silica Powder Crystalline Quartz Powder SiO2

Chemical vapor deposition

The method is to react a silicon source (such as silane or silanol) with oxygen at high temperatures and under the action of a catalyst to produce silica in a reactor. Based on the conditions of the reaction depending on the reaction conditions, the crystal structure, as well as the size of the particles of silica, can be adjusted. The advantages of chemical vapor deposition are controllable preparation conditions, high product quality, and high production cost.

Combustion synthesis

Combustion synthesis is a new method for the synthesis of crystalline silica. This method is the reaction of aluminum powder and oxygen at high temperatures to produce aluminum oxide. As the temperature rises, aluminum oxide further reacts with oxygen to form silicon dioxide. The advantages of combustion synthesis are simple equipment, convenient operation, and easy mass production, but the product purity and particle size may not be ideal.

Sol-gel method

Sol-gel method is to form silica sol or gel by mixing silicate and oxidant in aqueous solution, and then through hydrolysis, condensation, and other reactions. After drying and heat treatment, crystalline silica can be obtained. The advantage of the sol-gel method is that products with different particle sizes and morphology can be obtained by controlling reaction conditions, but the production cost is high.
