Product Description

Product Description:


White aluminum oxide is made from high purity Bayer process alumina. Raw materials and furnacing practices are carefully controlled to ensure its highest purity and optimum crystal structure. This guarantees a product with the ideal blocky grain distribution and bulk density needed for many applications.


It is used in long afterglow phosphors, three-color phosphors, abrasive materials, transparent ceramic lamps, high-pressure sodium lamps, catalyst carriers and EP-ROM windows. It can also be seen as part of the crystal, ruby and sapphire crystal, and electronic ceramics industries.


White aluminum oxide is used in several sectors due to its properties. These include electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper, medicine, and many others.





Raw manufacturers are able to provide high purity, high stability, and close texture due to their high hardness and consistently angular shapes. Moreover, they can achieve high processing speeds and high quality outputs without affecting the color of the workpiece.


Furthermore, our raw manufacturers are able to offer a level of customization rarely seen within third-party suppliers. This allows customers to create custom formulations and adjust their processes to meet their specific needs.


Finally, raw manufacturers are also well-equipped to manage inventory more effectively. This helps to reduce waste, eliminate stockouts, and gain better visibility of their own supply chain.

White corundum is an excellent senior ceramic material, which is widely used in industry because of its strong characteristics, such as high hardness, good wear resistance and corrosion resistance.


White corundum is ideal for several applications, including a grinding wheel, abrasives, and ceramic tools manufacturing.


Grinding wheel: White corundum grinding wheel show perfect performance in metal processing, due to its high hardness and reliable stability, which can meet different kinds of requirements for different occasions.


Abrasives: White corundum is also popular for being used for grinding and polishing of metal parts, or even tools such as knives.


Ceramic tools: Since white corundum has high hardness and excellent wear resistance, it is an ideal material for making ceramic tools.


Packing and Shipping:


White Aluminum Oxide is best packaged in 25kg sacks and palletized for shipping. The sacks should be well sealed and placed in a carton box for extra protection. The carton box should be labeled with the product name, quantity, date of manufacture and any other relevant information. During shipment, the product should be stored in a cool and dry place, away from moisture and direct sunlight.
