White aluminum oxide is made from high purity Bayer process alumina. To guarantee the highest quality and optimal crystal structure, raw materials and furnacing practices must be strictly managed. In addition, this type of aluminium oxide is crushed in such a way to increase bulk density by producing blocky grain distributions.
White aluminum oxide can also be applied in many areas, including long afterglow phosphors, three-color phosphor, abrasive materials, transparent ceramic lamp, high-pressure sodium lamp, catalyst carrier, EP-ROM window, crystal, ruby, sapphire crystal, electronic ceramics. Moreover, it can be used in various industries, such as electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper and medicine.
Raw materials are essential components of any manufacturing process. By sourcing raw materials from an in-house manufacturer, businesses can take advantage of the following benefits:
High Purity and Stability: Raw materials can be made with a high degree of purity and stability. This is especially true for close-textured materials, which have a high degree of consistency between individual components.
High Hardness and Angular Shape: Raw materials can be manufactured with a high degree of hardness and an angular shape. This ensures that the resulting product is strong and reliable, as well as looks aesthetically pleasing.
High Processing Speed and Quality: In-house manufacturing of raw materials allows for increased production speed and higher quality end products. As the raw materials are produced and used in-house, the process can be tweaked and perfected to achieve the desired quality.
No Change to Workpiece Color: Manufacturing raw materials in-house ensures that there is no adverse effect on the color of the workpiece. This is particularly important for items that need to maintain their original visual aesthetics.
Customization and Inventory Management: Raw manufacturers have the ability to create custom formulations and adjust their processes to meet specific customer needs. Additionally, raw manufacturers can also manage their inventory more effectively, reducing waste and eliminating stockouts.

White corundum is an excellent senior ceramic material widely used in industry for its high hardness, good wear resistance, and corrosion resistance. The following are the applications of white corundum:
White Aluminum Oxide is usually packaged in 25kg bags or 1000kg big bags. The bags are then placed in wooden pallets or paper pallets. The pallets are adequately secured with plastic straps, and then wrapped with a stretch film.
The shipping of White Aluminum Oxide can be done in two ways. First, the product can be shipped in bulk by sea. This is the most cost-effective shipping option. Second, the product can be shipped as individual bags by land or sea. This is more expensive but faster.
