What is Crystalline Silica Powder Crystalline Quartz Powder SiO2 ?

Crystalline Silica is essential to soil, sand, granite, and many other minerals. Quartz is the most common crystalline Silica. Quartz and quartzite are the other two forms of quartz. All three forms may be workers cutting, cutting, drilling, or grinding objects containing crystalline Silica. Crystalline Silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline Silica. It is also used to make glass, pottery, ceramics, bricks, and artificial stones.

Crystalline Silica is an abundant natural material. Crystalline Silica is found in stones, soil, and sand. It is also found in concrete, brick, mortar, and other building materials. Silica crystals come in several forms, of which quartz is the most common. Crystalline Silica dust is breathable crystalline Silica which can be inhaled through breathing. Please see the Osha silica standard for details about all occupational exposures to respirable crystalline Silica in construction work.

How is Crystalline Silica Powder Crystalline Quartz Powder SiO2 Produced? 
Silane combustion method
Silane combustion is a method of burning silane in air to produce silica. Silane is a flammable and explosive gas that can form silica and water when burned in the air. The advantages of this method are fast reaction speed, high production efficiency, and high purity of silica. Still, it requires high-purity silane and high temperature and high-pressure combustion conditions, so the production cost is high.
Sodium silicate acidizing process
Sodium silicate acidification is a method of acidifying sodium silicate solution to produce silica. Sodium silicate solution and acid (hydrochloric acids such as hydrochloric acid sulfuric acid or hydrochloric acid hydrochloric acid hydrochloric acid hydrochloric acid hydrochloric acid hydrochloric acid 3) mix, sodium silicate hydrolyzing sodium hydroxide and silicon dioxide. The advantages of this technique are the low reaction time, simple equipment, and easy operation.
 Still, it needs to use a lot of acids and bases for neutralization, and the generated wastewater is difficult to treat, so it has a certain impact on the environment.
Silicate ester hydrolysis method
The hydrolysis of silicate ester is a method of hydrolysis of silicate ester in water to produce silica. Silica and alcohol are produced by the hydrolysis reaction at a certain temperature and pressure by mixing the silicate ester with water in a certain proportion. The advantages of this technique are the low reaction temperatures and low-cost raw materials. Still, it must use much water and alcohol for washing and separation, and the generated wastewater is difficult to treat. Hence, it has a certain impact on the environment.
Metal silicate method
The metal silicate process is a method of decomposing metal silicates at high temperatures to produce silica. A metal silicate (such as sodium metasilicates) is mixed with a reducing agent (such as hydrogen or carbon) to undergo a reduction reaction at high temperatures to produce silica and metals. The benefit of this method is that the conditions for reaction are not too harsh, and the raw materials are inexpensive and easily accessible. Still, high temperature and reducing agents are needed, so the production cost is high.

Applications of Crystalline Silica Powder Crystalline Quartz Powder SiO2:
Crystalline silica is one of the main raw materials for making glass. The pure sodium silicate solution and silicate dioxide solution are mixed in the glass manufacturing process. The final glass product is obtained after melting, clarifying, and cooling. Crystalline silica can improve the hardness and strength of glass but also can control the optical properties of glass, such as light transmittance and refractive index.
Ceramic and enamel manufacturing
Crystalline silica is used as a colorant and opacifying agent in ceramic and enamel manufacturing. In the ceramic manufacturing process, adding a certain amount of silica can change the color of the ceramic and increase its hardness and wear resistance. At the same time, silica can also be used with other substances, such as metal oxides, to prepare a variety of ceramics and enamel products with different properties and appearances.
Electronics and microelectronics
Crystalline silica has a wide range of applications in electronics and microelectronics. It can be used as insulation, dielectric, semiconductor, and so on. In the process of IC manufacturing, silicon dioxide is one of the important materials for the preparation of thin film IC and semiconductor devices. It can be used as an insulation layer, mask, passivation layer, etc. In addition, silica can also be used as a photomask material to manufacture integrated circuits and microelectronic devices.
Catalyst and catalyst support
Crystalline silica can be a catalyst and carrier in many chemical reactions. Because silica has a high specific surface area and good thermal stability, it can maintain high activity and stability at high temperatures. In the petroleum industry, silica can be used as a catalyst for alkylation and isomerization reactions, etc., to improve the quality and yield of petroleum products. In addition, silica can also be used as a catalyst carrier in many organic synthesis reactions.
Polymer synthesis
Crystalline silica plays an important role in polymer synthesis. It can be incorporated into polymer materials to fill them to increase the strength of the material, wear resistance, heat resistance, and the dimensional durability of the product. In addition, silica can also be used as a crosslinking agent and modifier of polymer materials to prepare various polymer materials with different properties.
Biomedical field
Crystalline silica is also widely used in the biomedical field. It can be used as a drug carrier in drug delivery systems to improve efficacy and reduce side effects. At the same time, silica can also be used as a coating of biological materials for tissue engineering and biomedical devices. In addition, silica can also be used as a reagent and material in fields such as biomedical imaging and biosensors.
