High-purity magnesium oxide sand
1,High-purity magnesium oxide sand
2,Excellent heat
3,electrical insulation properties
4,mainly for high-temperature
High-purity magnesium oxide sandare electrically fused synthesized using high purity ZrO2,MgO,Cr2O3,TiO2,Al2O3 and Y2O3as starting materials,with high CaO,MgO or Y2O3 as stabilizer. All the products were purified with acid to eliminate iron.
