Refractories 
Description:
High purity magnesium sand is selected from natural high-grade magnesite ore for flotation purification, and is produced by light burning, fine grinding, ball pressing, and ultra-high temperature oil vertical kiln calcination.
Features:
High purity and good body density. It is a high-quality raw material for brick making and amorphous refractory materials.
Application:
High purity magnesia sand is a high-performance refractory material with high thermal conductivity, good high-temperature resistance, corrosion resistance, and insulation properties. It has extensive applications in multiple fields and industries, including but not limited to steel, metallurgy, building materials, national defense, medical equipment, cement, glass, and home appliance manufacturing.
