Brief information silicon metal: Industrial silicon is also called silicon metal is silver gray or dark gray metallic luster. Its high melting point, good heat resistance, high resistivity, high oxidation resistance, known as "industrial monosodium glutamate" is an indispensable basic raw materials for many high-tech industries. Grade: Si-2202, Si-3303, Si-421, Si-441, Si-553 Size: 0-10mm, 1-3mm, 2-5mm, 3-8mm, 100 mesh, 325 mesh and other grain size segments. Polysilicon, trichlorosilane with 20-100 mesh and 30-120 mesh, 40-160 mesh, 100-200 mesh, 45-325 mesh, 50-500 mesh of the size requirements of silica fume.
