Our Advantages

Silicon Powder: Enhancing Your Products

Silicon Powder: Enhancing the Performance of Your Products

Silicon Metal is typically produced in a size of 0-100 mm, but for most applications further size reduction is required. The optimum particle size depends strongly on the final application. Silicon metal powder is produced by crushing, milling, and classifying silicon material to obtain the required particle size.

Silicon Metal powder can be produced with a top cut for customers that only need to control the amount of coarse particles. It can also be produced with a top and bottom cut for customers that need to control both the amount of coarse and fine particles. The shape of the particles can also be altered by the technology used at the micronizing stage. Contamination-free micronizing is also possible for customers that cannot accept any contamination from the milling media.

Chemsize offers a range of metallurgical silicon powders that are carefully selected, crushed, milled to customer specifications and needs. Different purities and sizes are available to satisfy customer processing requirements and application needs. Products with customized chemistry and sizing can be produced on request.

Key Features:

• High purity Silicon metal Powder


• Customized chemistry and sizing


• Various particle sizes available
