Product Description

Product Description:

White Fused Alumina is commonly used in grinding applications which involve heat-sensitive alloys. This material, with its excellent friability and its cool cutting ability, is popular for use in precision grinding operations for high speed steels, segments and internal grinding wheels.

White Aluminum Oxide can serve as a raw material for the creation of a new type of phosphorus aluminum bactericide, VB12 pharmaceutical production adsorbent and active filter for paints. Furthermore, aluminum oxide is needed for the production of catalysts and anhydrous aluminum chloride. Lastly, it can be used for pharmaceutical, chemical and other industries.


This material is characterized as white crystal powder with a uniform particle size, a stable chemical property that is difficult to dissolve in acid and alkali, and a good sintering activity. Additionally, high purity aluminum oxide powder can be made from aluminum oxide.

In addition to its uses outlined earlier, aluminum oxide powder can be utilized for the production of long afterglow phosphors, three-color phosphor, abrasives, transparent ceramic lamps, high-pressure sodium lamps, EP-ROM windows, and ruby, sapphire crystals. Its applications are seemingly endless, reaching from fields like electronics and pharmaceuticals, to chemicals and FO petroleum.



A well organized supply chain can benefit raw material manufacturers in many ways. Improved supply chain efficiency and lower risk of supply chain disruptions can result in reduced shipping and handling costs. This can lead to competitive pricing and intellectual property protections, along with better communications with customers and reduced administrative overheads. It is also possible to increase agility in responding to market needs and to source raw materials more locally. Furthermore, this improved supply chain can lead to enhanced innovation capabilities as well as increased brand recognition through a focus on quality control.


Raw manufacturers also have complete control over the production process. This allows them to ensure the quality of their products and to quickly respond to any changes in demand. In addition, raw material manufacturers can benefit from high purity, stability, close texture, high hardness, angular shape, self-sharpening, strong grinding ability, small heat, high efficiency, acid and alkali corrosion resistance, high processing speed and high quality, as well as the fact that these materials won’t affect the color of the workpiece and will result in high production efficiency.


Technical Parameters:

White corundum is a compound of Al2O3, with a density of 3.95g/cm³ and a hardness of 9.0 Mohs hardness. It has a tripartite crystal structure and a compressive strength of 2,000 MPa, a tensile strength of 400 MPa and flexural strength of 480 MPa. It also has a thermal expansion coefficient of 8×10^-6 K^-1 and a thermal conductivity of 29 W/(m-K). White corundum has a high temperature stability and can withstand extremely high temperatures. It also has an electrical resistivity of about 10^14 Ω-cm. Its optical properties vary from transparent to translucent, and its refractive index is 1.76. Its colour usually appears white, but can also take the form of a light yellow, light blue, pink or other colors.



White corundum abrasive is suitable for all kinds of high-end products, process or hardware products surface beautification treatment. It has a variety of uses:

  • 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 in several ways:

  • As solid coated abrasive tools, wetting or dry sand blast.
  • As super fine grinding, polishing and making high-grade refractory materials for crystal, electronic industry.
  • For crystal frosting of glass products, matte effect of engraved plastic products, plush processing and effect pattern of denim and other special fabrics.
