Silicon powder with expanding applications. You can specify the particle size and materials used based on your required specifications.

Depending on the application, silicon raw materials and grinding particle sizes can be flexibly selected and combined. Materials: Metal silicon (1101/2202/3303/441/553) Metallurgical-grade polysilicon (4N/5N/6N) Particle size: You can specify within the range of D50=5µm to 50µm. Additionally, we can accommodate a wide range of requests from a few millimeters to sub-micron (nano) levels. (We will provide a price estimate based on particle size, silicon purity, and quantity.)
