Brown Fused Alumina

Brown fused alumina, also known as corundum, is an extremely hard material that is made by burning bauxite in an electric arc furnace. Its unique composition makes it very stable, tough and useful in blasting applications. It also has low iron oxide content, which makes it a good choice for use in non-iron processes.

Brown fused alumina is used for a wide range of applications, including as raw material for coated and bonded abrasives, grinding wheels, and sandpaper. It's also an important component of water jet cutting and filtration systems. Its other uses include making molds for precision casting.

Brown fused alumina is produced by reduction fusion of high-quality bauxites in electric arc furnaces. It is hard and tough, and is a common abrasive, polishing, and refractory materials. It is crushed, sized, and sold in various grades.

Brown fused alumina has a wide range of applications and is available in several different forms. It can be hydrated or calcined, and the degree of calcination determines its physical and chemical properties. Alumina crystals are approximately one-sixth of an inch in diameter.

In addition to its excellent toughness and compression strength, Brown aluminum oxide is also known for its low coefficient of thermal expansion. Moreover, it is highly resistant to corrosion and oxidation, and has a high degree of thermal and chemical stability. These properties make it well-suited for a wide range of applications and industries.

These materials are stable at all temperatures. They are described by electron microscopy. The most stable phase of alumina is a-alumina, which has a trigonal lattice. The oxygen planes are stacked ABAB along the c-direction and Al ions fill two-thirds of the octahedral interstitial positions.
