Our Advantages

Silicon Powder: Enhancing Product Performance

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.

Key Features:

• Customizable particle sizes for specific applications


• Contamination-free micronizing available


• Range of purities and sizes to meet processing needs


• High purity for various deposition processes


• Available in nanoparticle sizes for high surface areas

Product Range:

Chemsize offers a variety of metallurgical silicon powders, including high purity Silicon Metal Powder ideal for sputtering targets, CVD, PVD processes, water treatment, fuel cells, and solar applications. Our products are available in various particle sizes, including nanoscale options.
