Product Description

Product Description:

White aluminum oxide is made from high purity Bayer process alumina. Raw materials and furnacing practices must be strictly controlled in order to ensure the highest possible purity and optimum crystal structure. It is then crushed in a way to produce a blocky grain distribution with increased bulk density.

It has the appearance of white crystal powder, with a uniform particle size and stable chemical properties. Its difficulty in dissolving in acid and alkali as well as its enhanced sintering activity make it an attractive material.

Aluminum oxide can be used as a raw material in the production of a variety of other substances, such as long afterglow phosphors, three-color phosphor, abrasive materials, transparent ceramic lamps and high-pressure sodium lamps. It can also be used as a catalyst carrier, EP-ROM window, crystal, ruby and sapphire crystal, and electronic ceramics.

The range of applications for aluminum oxide is vast, coverings fields such as electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper and even medicine.




Our product features high purity and stability, with a close texture and high hardness. Its angular shape gives it excellent self-sharpening strength and grinding capabilities, whilst the heat produced during processing is kept to a minimum. In addition, our product shows excellent acid and alkali corrosion resistance, as well as being noted for its high processing speed and quality, which ensures there is no discoloration of the workpiece.



We use only high quality raw materials, which are subject to strict quality control. All of our products are original designs and we have ample stock, allowing us to satisfy even large orders quickly. We oversee the production process closely, to ensure efficiency and cost savings. We are happy to customize our products to client specifications and can manage inventory in a responsible, sustainable way. Furthermore, our quality assurance and reduced lead times lead to improved supply chain efficiency.

We source our raw materials locally whenever possible, helping both the environment and our local economy.

White corundum abrasive is suitable for many high-end products, process or hardware products surface beautification treatment. It can be used in many ways, such as solid coated abrasive tools, wetting or dry sand blast, and even for super fine grinding. It can also be used to make high-grade refractory materials, crystal frosting of glass products, matte effect of engraved plastic products, plush processing and effect pattern of denim and other special fabrics.

When used to process iron workpieces, it can derust, decontaminate, remove oxidation skin, and increase the adhesion of the coating. When used to process aluminum workpieces, it can remove oxidation skin, strengthen the surface, and have a glossy effect. For copper workpieces, removing oxidation skin can give it a matte effect.
