Crystalline silica powder has a wide range of applications. High purification and ultrafineness are its important upgrade directions.

Microsilica powder, also known as quartz powder, is a functional filler. According to different production processes, microsilica powder can be divided into four types: crystalline silica powder, fused silica powder, active silica powder, and cristobalite silica powder. Among them, crystalline silica powder is a silica powder material refined from natural high-purity quartz ore through multiple processes of cleaning, grinding, screening, and impurity removal.

Crystalline silicon is slightly pink and white, pure in quality, and has the characteristics of stable chemical properties, excellent electrical properties, controllable particle size distribution, and good wear resistance. It is widely used in electrical insulation materials, copper-clad laminates for home appliances, precision casting, epoxy plastic sealing materials, Paints and coatings, special ceramics, optical glass, functional rubber and other fields. Plastic packaging technology is the mainstream method for producing large-scale integrated circuits. In recent years, driven by the integrated circuit industry, the epoxy plastic packaging market has grown rapidly, providing broad space for the development of the crystalline silicon micro industry.

According to the “2023-2027 China Crystalline Silica Powder Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center It shows that the crystalline silica powder market started early, and the process technology and production equipment are relatively mature, so the market price is often lower than other types of silica powder. However, crystalline silica powder has high hardness and poor dispersion. In order to improve its performance, high purification and ultra-fineness will become an important development trend of crystalline silica powder.

Microsilica powder is an important raw material for semiconductor production. In recent years, benefiting from the development of semiconductors, copper-clad laminates and other industries, the market size of microsilica powder has continued to expand, reaching more than 2.45 billion yuan in 2021, a year-on-year increase of 17.6%. my country is a major producer and consumer of silica powder. However, due to technical and financial constraints, domestic silica powder is of low quality and poor stability. The products are mainly mid- to low-end crystalline silica powder and fused silica powder. The demand for high-end silica powder is still high. Relying on imports, such as spherical silica powder and ultrafine silica powder.

Crystalline silica powder is one of the mainstream silica powders in the market. my country’s crystalline silica powder suppliers include Anhui Yishitong, Chongqing Jinyi Silicon Materials, Zhejiang Huafei Electronics, Donghai Botai, etc. Crystalline silica powder can be divided into three types: high-purity crystalline silica powder, electronic-grade crystalline silica powder, and ordinary crystalline silica powder. At present, there is still a certain gap between my country’s high-end crystalline silica powder production technology and the international advanced level, and the industry The structure is in dire need of upgrading.

Industry analysts said that crystalline silica powder is one of the mainstream silica powders in the market and is widely used in electronic materials and copper-clad laminates for home appliances. , epoxy plastic sealants, functional rubber and other fields. In recent years, with the growth of my country’s economy, the market demand for crystalline silica powder has continued to grow. The price of crystalline silica powder is low, but it has problems such as poor dispersion and high hardness. In the future, under the consumption upgrade, crystalline silica powder needs to be upgraded in the direction of ultra-fine and high purification.
