Brown Fused Alumina

Brown Fused Alumina

Brown fused alumina is a hard, durable, and high-refractory abrasive, used for sandblasting, metal preparation, and other high-performance applications. It has low thermal expansion, strong fluidity, and corrosion resistance, making it ideal for a wide variety of abrasive processes. As a result, it has become an important component in a variety of industries. The market for this abrasive material is expected to grow in the upcoming years.

Brown fused alumina is produced through a process that involves partial impurity removal, and then fusing and purifying in an electric arc furnace. It can be manufactured at temperatures of up to 2000 deg C. This allows for a high purity product. Additionally, it can be manufactured to meet individual specifications. In addition, it can be used for a variety of refractory applications, including ceramic shapes and blasting refractory.

Typically, brown fused alumina is made from a high-quality bauxite raw material. This material is then smelted in a electric arc furnace. During this process, the iron oxide and carbon material are reduced to produce an alumina product. Due to its high alumina content, it also has a low melting point, making it an ideal surface hardening agent for a range of metals. Since it is almost iron-free, it is environmentally friendly. Compared to other abrasives, it has superior oxidation resistance and high tensile strength. Also, it has a relatively uniform particle size and chemical stability. Moreover, it has a very low coefficient of linear expansion.

With the growing need for high-quality abrasives, the demand for brown fused alumina is increasing. Currently, the market for this abrasive material has seen substantial growth in the Asia-Pacific region. This increase is largely due to the building and construction industry, and the increasing need for refractory products in the region. Moreover, the increased production of steel in this region has also led to increased demand for refractory materials, including high-alumina products. Despite this, manufacturing costs of brown fused alumina are expected to restrain its growth.

Currently, the largest producer of brown fused alumina is China. Despite this, global demand is projected to rise in the coming years, as a result of the rising need for alumina in the refractory industry. However, the shortage of essential raw materials has negatively affected the production of refractory products. Therefore, researchers are looking for alternative sources of alumina.

One such alternative is chilcon, a ferroslag by-product. Chilcon is a heavier and harder abrasive, with high wear and tear characteristics. For this reason, it is particularly useful for cleaning stainless steel and non-ferrous metals. Similarly, it can be used for a wide variety of refractory and flooring applications. Moreover, chilcon is imported in significant quantities from Brazil.

Alumina is a mineral, derived from a variety of ores. It has a wide range of uses, including sandpaper, coatings, and metal preparation. While it is commonly used for these purposes, it is also used in the industrial sector, and as a refractory material. White fused alumina, on the other hand, is a highly pure, dense mineral.
