What is the development trend of silicon powder?

（1） Ultra fine and high purity silicon powder has become a hot spot in the industry

Ultrafine silicon powder is a new material developed in recent years. Superfine silicon powder has the characteristics of small particle size, large specific surface area, high chemical purity and good filling ability. It has been widely used in many fields, such as copper clad laminate, adhesive, rubber, coating, engineering plastics, medicine, paper making, daily chemical and so on, because of its excellent properties of non disorder, reinforcement, thickening and thixotropy. It also provides the basis and technical guarantee of new materials for the development of related industries and enjoys the reputation of "industrial monosodium glutamate" and "origin of material science". High purity silicon powder generally refers to the silicon powder with SiO2 content higher than 99.9%, which is mainly used in IC integrated circuit and quartz glass industries. Its products are widely used in large-scale and ultra large scale integrated circuit, optical fiber, laser, aerospace, military, and it is an indispensable important material for high-tech industry. Some developed countries take it as a strategic goal. High purity silicon powder will become the basic material of the electronic industry in the 21st century, the demand will grow rapidly, and has a good market prospect.

（2） Spherical silicon powder has become the development direction of the industry

At present, there are few enterprises that can produce spherical silicon powder, only the enterprises with higher technology have the production capacity. In recent years, the computer market and network information technology market have developed rapidly, CPU integration is getting bigger and faster, and the computer and Internet users are growing. As a technology support, microelectronics industry, for large-scale and large-scale integrated circuit packaging materials, not only requires ultra-fine, but also requires high purity and low radioactive element content, especially for particles The spherical requirements are put forward for the shape.

（3） Surface modification technology deepening development

With the continuous development of downstream application market, the quality and non disorder requirements of nonmetallic mineral powder materials are constantly improving. At present, the technology of nonmetal mineral powder materials in China is not satisfied with the application needs. The surface and interface modification technology of powder will become one of the main development directions of non-metallic mineral powder processing technology. The surface modification of powder refers to the treatment of the surface or interface of powder materials by physical, chemical and mechanical methods, and the chemical properties of the surface of the powder materials are purposefully changed to meet the needs of the development of modern new materials, new technologies and new technologies. At present, the main methods used in the surface modification of nonmetallic mineral powders are surface chemical coating, precipitation reaction coating, intercalation modification, etc.
