Fused Silica Powder Fused Silica Grain

Fused Silica Fused Silica Grain Fused silica powder fused silica flour Fused Silica is the selection of high-purity quartz at very high temperatures from melting, with a high silica content, and low thermal conductivity. High insulation characteristics, chemical stability. all the fused silica powder or fused silica grain can be dived into A and B class Grade A: SiO2: 99.9%min Grade B: SiO2: 99.8%min Particle size: A: 5-50mm, 0-0.5mm, 0.5-0.2mm, 0.2-0.1mm, 0.5-1mm B: -4+10mesh, -10+20mesh, -20+50mesh, -30+50mesh, -50+100mesh, -120F, -200F, -325F, -400F, -600F Or in accordance with customer's request.PH5.8 Specs0.1-5MM ComponentSiO2: 99.99%-99.90%; Fe2O3: 7ppM max Li2O: 1.0 ppM max; Al2O3: 30 ppM-100ppM; K2O:9 ppM max; Na2O: 11ppM max; Uses : Refractories, Precision Casting, semiconductor packing, special coatings, ceramics, molds, and other industries.
