Refractory Raw Material Brown Corundum

Refractory raw material brown corundum is made from high-quality high-aluminum ore through high-temperature smelting, cooling, crushing, screening, and water washing. It has high strength, excellent chemical stability, wear resistance, acid and alkali corrosion resistance, and high temperature resistance. Brown corundum is widely used in refractory material manufacturing, grinding wheels, abrasive tools, chemical catalysts, electrolytic aluminum, aerospace and other fields.

Chemical composition of brown corundum: Al2O3≥95.0%, SiO2≤1.0%, Fe2O3≤0.3%, Na2O≤0.35%, CaO≤0.35%. It has high purity, low oxides, uniform distribution and good crystallinity.

It can be customized according to the needs of different users. The main specifications are: 0-1mm, 1-3mm, 3-5mm, 5-8mm, etc.

Products Advantages

(1) High strength: Brown corundum has high hardness, high density, high hot and cold strength, etc., and has better wear resistance and corrosion resistance in harsh environments such as high temperature and thermal stress;

(2) Acid and alkali corrosion resistance: Brown corundum performs relatively well in strong acid and alkali corrosion environments;

(3) High temperature resistance: Brown corundum has a high melting point, maintains high temperature for a long time, and is not easy to melt;

(4) Excellent chemical stability: Brown corundum reacts less with various metals and compounds and is an ideal dielectric material;

(5) Uniform particle size distribution: The particle size distribution of brown corundum is uniform, making it approximately equal-diameter spherical, and has excellent performance in wear resistance, corrosion resistance and high temperature performance;

(6) High purity: The high purity and chemical stability of brown corundum can ensure that it is harmless to humans and nature.

(7) Wear resistance: Brown corundum has high hardness, strong wear resistance, uniform particle size and smooth surface;

Products Applications

(1) Manufacturing brown corundum refractory products: Brown corundum can be used as the main raw material for manufacturing various types of advanced refractory materials, such as high alumina bricks, asbestos-free perovskite bricks, direct bonded magnesia carbon bricks, amorphous refractory materials, etc.;

(2) Manufacturing ceramic products: Brown corundum can be used as the main raw material for ceramic glazes, ceramic raw materials, and ceramic precious metal pigments;

(3) Manufacturing grinding wheels, abrasive tools, and sandblasting materials: Brown corundum can be used as one of the main materials for manufacturing high-quality grinding wheels, abrasive tools, and sandblasting materials;

(4) Manufacturing of cermets: Brown corundum can be used as the main raw material for manufacturing cermets and is widely used in the manufacturing processes of aluminum, steel and chemical iron;

(5) Manufacturing electrical insulation materials: Brown corundum can be used to manufacture insulation materials for high-voltage electrical equipment, such as transformers, electrical industrial ceramics, etc.

(6) Other fields: Brown corundum is widely used in coatings, chemical catalysts, refining catalysts, aerospace and other fields.
