Product Description

Product Description:


White aluminum oxide is a high purity material produced using the Bayer process. The production of this material is strictly controlled to ensure optimal purity and crystal structure. The material is crushed in a specific way, in order to produce a blocky grain distribution with high bulk density.


This white aluminum oxide has a wide range of uses, from long afterglow phosphors and three-color phosphors, to abrasive materials and transparent ceramic lamps. It is used to make high-pressure sodium lamps, EP-ROM windows, rubies, sapphires, and many electronic ceramics. Industries such as electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper, medicine, and many others, all use this material.




Raw Manufacturers offer products of high purity, high stability, close texture, high hardness and angular shape, while offering a fast processing speed and delivering a high quality, all without affecting the original colour of the workpiece.


Moreover, raw manufacturers can provide customized solutions according to customer needs without depending on other third-party suppliers. This level of customization is hard to achieve anywhere else.


In addition, raw manufacturers can also effectively manage their inventory due to the visibility into the supply chain. This can minimize waste and eliminate stockouts.

White corundum is an excellent senior ceramic material, which is widely used in industry due to its remarkable properties: high hardness, good wear-resistance and corrosion resistance.


One of the major applications of white corundum is in the manufacturing of grinding wheels. It is the best finishing tool available for metal processing. Its durability and high hardness make it suitable for all kinds of processing occasions.


White corundum is also used as an abrasive, mainly for grinding and polishing different metal surfaces and for making kitchen knives and other tools.


Finally, white corundum is commonly used to manufacture ceramic tools due to its strong hardness and excellent wear-resistance.


Packing and Shipping:


White Aluminum Oxide is normally packaged in 25kg bags or big bags. For safety reasons, all bags are shrink-wrapped to prevent any dust from leaking out. Special packaging solutions are also available upon request.


White Aluminum Oxide is normally shipped by truck, train or container. Delivery time depends on the destination and the method of transport selected. All shipments include a full set of documents, including a safety data sheet and a certificate of analysis.
