High-Purity White Fused Alumina For Refractory Applications

White Aluminium Oxide is a blasting media that is often used on products with softer coatings. It is preferred for use on surfaces that cannot come into contact with other forms of metal oxides, such as brown aluminum oxide. It is often used for microdermabrasion on metal surfaces.

Products Description

White corundum, also known as white aluminum oxide or white fused alumina, is a type of abrasive material produced by melting high-purity alumina and adding additives such as chromium oxide, magnesium oxide, or titanium oxide. It is characterized by its high purity, hardness, and friability, making it ideal for applications such as grinding, polishing, blasting, and precision casting. White corundum is also widely used in the manufacture of refractory materials, porcelain, ceramics, and other high-temperature resistant products. Its bright white color and uniform particle size make it a popular choice for decorative applications such as sandblasting and etching.
