Advantages of Calcined Brown Fused Alumina

Posted by Tom Brady on October 27th, 2022

Calcined brown fused alumina also known as electrocorundum, and aluminum oxide are obtained minerally while combining bauxite in an electric arc furnace. Its main constituent is alumina Al2O3. Calcined brown fused alumina is an ecologically clean and very hard material. It is used in the production of abrasives, and in dry & wet blasting applications where it is refillable. Due to sharp, & self-renewable edges, calcined brown fused alumina is highly grinding. The brown fused alumina is free of not respirable crystalline silica.

How Calcined brown fused alumina is made

Brown Fused Alumina is called Brown Fused Aluminium Oxide or Brown Corundum. It is a material produced by the fusion process of bauxite which is a source of aluminum oxide and other fillings and crumpled and screened into grits of diverse sieving distribution. It is a brown, very dense, tough, harder, heat-resistant, abrasion-resistant substance widely used for abrasives, and sandblasting purposes

Calcined Alumina Oxide Resources

High Transparency Abrasive Grains

Calcined brown fused alumina is purer than the other fused aluminum oxide products with the exclusion of fused white aluminum oxide. When milled, calcined aluminas hold the chemistry of the unmilled crude closely than fused aluminum oxide. Precision-grade Calcined brown fused aluminacan be used in glass, metal lapping & polishing as well as on coated abrasive tapes. The characteristics of calcined alumina that differentiate it from fused aluminum oxide grains are its shape & purity. Calcined alumina grains are usually composed of single platey crystals, white fused aluminum oxide grains tend to be fractions of larger crystals & blocky in shape. A calcined crystal is supposedly a 6-sided disk with a thickness of one-fifth of its diameter. Customized sizes and compounds are readily available. Calcined brown fused aluminais made by fusing & purifying in a pouring electric arc furnace at a high temperature of over 2200° C with higher quality bauxite, carbon substantial, and iron filings as the chief materials. The raw material of Calcined brown fused aluminais aluminum oxide powder. It can be notable from the smelting furnace; it can be separated into dumping furnace which is also called tilting furnace and fixed furnace. Compared with the fixed furnace, the manufacture of brown fused alumina in a tilting furnace is a little better. Its appearance is more seemingly in the content of SiO2. The content of SiO2 in the manufacture of brown fused alumina in a tilting furnace is lesser than that of the fixed furnace.

Abrasive grade Calcined brown fused alumina

Calcined brown fused aluminais made from Calcined Bauxite. It is a harder and tough material, used in the business of grinding wheels and coated products. These grains are used for shot blasting and in polishing media. It is obtainable in grit sizes for abrasive applications & group grits for refractory applications.
