Product Description

Product Description:

Pure White Alpha Aluminum Oxide Media For Lapping Powder

White aluminum oxide is a high purity Bayer process alumina produced by carefully controlling raw materials and furnacing practices. It is typically crushed to produce blocky grain distributions with a higher bulk density. This substance has a white crystal powder appearance with uniform particle size, is stable chemically, has a good crystal phase stability, is difficult to dissolve in acid and alkali, and has good sintering activity.

Aluminum oxide is a versatile material often used in electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper, medicine, and many other fields. It is can act as a long afterglow phosphor, three-color phosphor, abrasive material, transparent ceramic lamp, high-pressure sodium lamp, catalyst carrier, EP-ROM window, crystal, ruby, sapphire crystal, and electronic ceramics.

Further, the raw material can also be used to prepare high purity aluminum oxide powder.



Product Advantage

Our product is characterized by high purity, stability and close texture. It also features a high hardness and angular shape which provides superior self-sharpening, grinding ability, low heat generation and high efficiency. Moreover, it is resistant to acid and alkali corrosion. Furthermore, it improves the production speed and quality while ensuring the color of the workpiece remains intact.

Supplier Advantage

Working with our company, you can expect the highest quality raw materials and strict quality control. We practice production originality and maintain sufficient inventory at all times. A comprehensive control system is put in place to ensure efficient production processes, cost savings, customization options and efficient inventory management. In addition, our commitment to sustainability and quality assurance will reduce lead times, improve supply chain efficiency and enable us to source local raw materials.


Technical Parameters:

The chemical constitution of Al2O3 includes more than 99.4 percent Al2O3, 0.04 percent SiO2, 0.04 percent Fe2O3 and 0.30 percent Na2O.

The physical property of Al2O3 is white in colour, with 9 Mohs hardness, 3.9 g/cm3 true density, 1.60~1.95g/cm3 bulk density and Ig-Loss Below 0.09 percent.



White corundum abrasive is suitable for all kinds of high-end products, process or hardware products surface beautification treatment. It can make iron workpiece derusting, decontamination, remove oxidation skin, increase the adhesion of the coating. It can make aluminum workpiece remove oxidation skin, surface strengthening, glossy effect. It can make copper workpiece remove oxidation skin for achieving matte effect.

It can be used as solid coated abrasive tools, wetting or dry sand blast. It can be used as super fine grinding, polishing and making high-grade refractory materials for crystal, electronic industry.

It can be used for crystal frosting of glass products, matte effect of engraved plastic products, plush processing and effect pattern of denim and other special fabrics.
