Zhejiang Kaihua Yuantong Silicon Industry Co., Ltd. was specialized in the research and manufacturing concerning silicon metal, silicon metal powder. 

The main products are silicon metal lumps (2202, 3303, 411, 421, 441, 553 etc.), silicon metal powder (2mm~10μm). We principally produce the chemistry grade of silicon metal powder used for organicsilicon monomer, trichlorosilane and Monocrystalline silicon.Our products can also be applied in the industries regarding refractory, electron, optics, building material, mechanism, chemical, metallurgy, etc.

Our products gains its protection status under ”PDO” (protected designation of origin), besides of that, we are certified by ISO9001:2000 quality system and are im-export authorized in 2003, the products are mainly exported to Japan, Korea, India regions and so on.

Main mesh sizes are 425μm-150μm(40mesh-100mesh);500μm-180μm(30mesh-80mesh)250μm-140μm(60mesh-110mesh);125μm-74μm(120mesh-200mesh);-74μm(-200mesh)-44μm(325mesh); 5μm-1μm(2500mesh-12500mesh).
