Properties of white corundum

The color is white, the hardness is slightly higher than brown corundum, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. It is suitable for precision casting, refractory materials, grinding, sandblasting, polishing materials, spraying materials, chemical catalyst carriers, special ceramics, etc.

Production process of white corundum

White corundum is made of high-quality aluminum oxide powder as the main raw material, which is smelted at high temperature in an electric arc furnace.

White corundum micropowder is made of high-quality aluminum oxide powder as the main raw material, which is melted at high temperature in an electric arc furnace to form white corundum blocks, which are crushed into small pieces by a jaw crusher, and secondary crushed by a ball mill to make the particles smaller, and then pickled. Impurities are removed, siphon is segmented, stirred and precipitated to extract different models on time, and then dried and sieved through sedimentation to loosen.

The use of white corundum

1. Surface processing: metal oxide layer, carbide black skin, metal or non-metal surface rust removal, such as gravity die-casting mold, rubber mold oxide or release agent removal, ceramic surface black spots, uranium color removal, painting Rebirth.
2. Beautification processing: all kinds of gold,K gold jewelry, matte or matte treatment of precious metal products, matte processing of crystal, glass, corrugated, acrylic and other non-metallic materials, and can make the surface of processed objects into a metallic luster.
3. Etching process: jade, crystal, agate, semi-precious stones, seals, elegant stones, antiques, marble tombstones, ceramics, wood, bamboo etc.
4. Pre-processing: Teflon (TEFLON ), PU , ​​rubber, plastic coating, rubber roller ( ROLLER ), electroplating, metal spray welding, titanium plating and other pre-treatments to increase surface adhesion.
5. Burr processing: removal of burrs from bakelite, plastic, zinc, aluminum die-casting products, electronic parts, magnetic cores, etc.
6. Stress relief processing: stress relief processing for aerospace, national defense, and precision industry parts, rust removal, paint removal, matting, and renovation
