Schmelzmagnesia

Products with natural high-purity fused magnesia fired at by 3000KVA large crystal fused magnesia. Crystallized, with a compact, high melting point, chemical stability, large compressive strength, insulation performance, high resistance to erosion, corrosion resistance, is the senior basic refractories. With high purity, calcium silicon than good, a large crystal size, physical and chemical characteristics of stable performance, mainly used in metallurgy, chemical industry, electronics, aerospace and defense industries. indexTypeL.O.I(max.)SiO2(max.)Fe2O3(max.)Al2O3(max.)CaO(max.)MgO(min.) g/cm³(min.)DFM-99 0.1%0.2%0.2%0.10%0.4%99%3.55DFM-98.50.2%0.35%0.3%0.15%0.8%98.5%3.54DFM-98 0.2%0.5%0.5%0.20%1.0%98%3.50DFM-97.50.2%0.7%0.5%0.50%1.2%97.5%3.50DFM-97 0.3%1.0%0.7% 0.30%1.4%97%3.50
