1. Concept of mesh number
The mesh number of silicon metal Powder refers to the grade determined by the size of silicon metal Powder passing through the screen. The smaller the mesh number, the larger the particles; the larger the mesh number, the finer the particles. Generally, the mesh number of metallic silicon powder is between 50 mesh and 1000 mesh. The larger the mesh number, the finer the particle size of metallic silicon powder, and is suitable for industries that require finer particles.
2. Mesh classification and application of metallic silicon powder
①. Below 20 mesh: Mainly used in anti-skid materials, ceramics, electronics industry and other fields.
②. 20-100 mesh: suitable for chemical industry, building materials, coatings, plastics, rubber, glass and other fields.
③. Above 100 mesh: suitable for the preparation of advanced ceramics, advanced refractory materials, optical glass, electronic materials and other fields.
3. The relationship between the mesh number of silicon metal Powder and the performance of silicon metal Powder
The mesh number of metallic silicon powder is one of the important parameters to measure the particle size of metallic silicon powder. The higher the mesh number, the smaller the particle size of metallic silicon powder, the specific surface area also increases accordingly, and it has higher chemical activity and surface energy. At the same time, the higher the mesh number, the fluidity of metallic silicon powder will also decrease. Therefore, during the application process, silicon metal Powder of different mesh sizes needs to be selected according to the requirements of different fields.
In short, the mesh number of metallic silicon powder is one of the important parameters to measure the particle size of silicon powder and has an important impact on the performance and application of metallic silicon powder. In practical applications, silicon metal Powder of different mesh sizes needs to be selected according to specific requirements to achieve the best application effect.
