Product Description

Product Description:

White Fused Alumina is a remarkable material because of its strong friability and cool cutting ability. It is applied in precision grinding of heat sensitive alloys, high speed steels, segments, and internal grinding wheels.


White Aluminum Oxide is also a valuable by-product as it can be used to produce pesticides, adsorbents for pharmaceuticals, and active filters for paint. Its chemical property remains stable, and it is difficult to dissolve in any acid or alkali. Furthermore, it has good sintering activity making it a great resource to prepare high purity aluminum oxide powder.


White Aluminum Oxide can also be used in long afterglow phosphors, three-color phosphors, abrasives, transparent ceramic lamps, high-pressure sodium lamps, catalyst carriers, EP-ROM windows, crystals, rubies, sapphires, electronic ceramics, electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper, and medicine.



Improved Supply Chain Efficiency

Improving supply chain efficiency has several benefits for raw manufacturers. Not only do they save on shipping and handling costs, they also reduce the risk of supply chain disruptions and obtain competitive pricing. This can result in reduced administrative overheads, increased agility in responding to market demands, increased capacity for innovation, and improved brand recognition through focus on quality control.


Control over Production Process

Having complete control over the production process gives raw manufacturers the ability to source raw materials locally, and also ensures a high degree of quality control. This also makes it possible for them to react quickly to any changes in demand without sacrificing on the purity, stability or other important characteristics, such as close texture, hardness, angular shape, self-sharpening, grinding capability, and corrosion resistance.


Processing Speed and Quality

Crucially, this improved efficiency does not come at the cost of production speed or quality. On the contrary, raw manufacturers benefit from improved processing speeds and higher-quality products, without any effects on the resulting work piece colour or other characteristics.


Technical Parameters:

White corundum, classified as Al2O3, is characterized by a density of 3.95g/cm³ and a Mohs hardness of 9.0. Its crystal structure follows a tripartite symmetry and its compressive strength can reach up to 2,000 MPa, its tensile strength 400 MPa and its flexural strength 480 MPa. The thermal expansion coefficient is 8×10^-6/K and its thermal conductivity is 29 W/(m-K). White corundum's thermal stability is extremely high, capable of withstanding high temperatures and its electrical resistivity typically reaches 10^14 Ω-cm. In terms of its optical properties, white corundum is either transparent or translucent, with a refractive index of 1.76, and is often white, though may sometimes appear in a light yellow, light blue, or pink.



White corundum abrasive has a wide range of applications. It is suitable for processing and hardware products surface beautification treatment, making it ideal for high-end products. It has several uses, such as:

  • For iron workpieces, it can remove rust, decontaminate, and increase the adhesion of the coating.
  • For aluminum workpieces, the abrasive can remove oxidation skin and strengthen the surface of the material, creating a glossy effect.
  • The abrasive is also suitable for copper workpieces, creating a matte effect when the oxidation skin is removed.

The abrasive can also be used as sandblast tools, both when wet and dry, and for making high-grade refractory materials in the crystal and electronic industry. Additionally, it can be used for frosting glass products, creating a matte effect of engraved plastic products, and making plush effect patterns on denim and other special fabrics.
