Crystalline silicon powder is a subdivision product of angular silicon powder, and the market share of high-purity crystalline silicon powder is expected to increase
Angular silicon powder refers to the shape of irregular angular silicon powder, according to different preparation methods, can be divided into two types: molten silicon powder and crystalline silicon powder. Crystalline silicon powder, also known as crystalline silicon powder, refers to the silicon powder made of natural white quartz as raw material and grown by crystallization at high temperature. Crystalline silicon powder has the advantages of good chemical stability, controllable particle size distribution, excellent electrical properties, good wear resistance, etc., and is widely used in engineering plastics, coatings, fine ceramics, electronic and electrical fields.
Angular silicon powder is a spherical silicon powder raw material, which contains oxide groups and substituent groups on its surface, and has the characteristics of high surface activity, large specific surface area, wide particle size distribution and high technical maturity, and can be used to manufacture electronic packaging materials. In recent years, with the growth of application demand, the development speed of the continental angular silica powder industry has accelerated. In 2023, the market size of horn-shaped silicon powder in mainland China will reach nearly 800 million yuan. In the future, with the continuous expansion of the market space of angular silicon powder, crystalline silicon powder will be used as its subdivided product, and the prosperity of the industry will be improved.
Crystalline silicon powder mainly includes filler-grade crystalline silicon powder, electronic-grade crystalline silicon powder and high-purity crystalline silicon powder. High-purity crystalline silicon powder refers to high-performance crystalline silicon powder with a silicon oxide content of more than 99.9%, which has the characteristics of good insulation, yellowing resistance and low oil absorption, and can be used to manufacture insulating materials. At present, a number of enterprises in mainland China have laid out the R&D and production track of high-purity crystalline silicon powder industry, and their market share will increase with technological progress in the future.
According to the "2024-2028 China Crystalline Silicon Powder Market Monitoring and Future Development Prospect Research Report" released by the Xinsijie Industry Research Center, crystalline silicon powder is mainly used in engineering plastics, coatings, precision ceramics, electronic and electrical and other fields. In the field of engineering plastics, crystalline silicon powder can be used to manufacture PVC plastics and PP plastics, in the field of coatings, it can be used to produce anti-corrosion coatings, insulating coatings, etc., and in the field of electronic and electrical, it can be used to manufacture high-purity silicon wafers. In the future, with the continuous expansion of the application range, the application demand for crystalline silicon powder in mainland China will become increasingly strong.
The main manufacturers of crystalline silicon powder in mainland China include Baitu Co., Ltd., Novoray New Materials, Huawei Silicon Powder, Lister Silicon Powder, etc. Novoray is a representative enterprise of crystalline silicon powder in mainland China, and its products have been widely used in the production process of epoxy plastic packaging materials for chip packaging.
Industry analysts said that as a subdivision product of angular silicon powder, crystalline silicon powder is widely used in many fields, and the development prospect of the industry is good. In recent years, with the advancement of technology, the market share of high-performance crystalline silicon powder in mainland China has been increasing. It is expected that in the future, with the continuous efforts of local enterprises and the continuous growth of market demand, the development speed of the crystalline silicon powder industry in the mainland will accelerate.
