Application Field Of Brown Fused Alumina in Industrial Field

Fused alumina is an ecological material – the content of the Al2O3 in the material varies between 84% and 95% depending on your needs. Brown corundum does not contain lead and silica, thanks to that it is safe for the operator.

Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.

Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000oC. A slow solidification process follows the fusion, to yield blocky crystals. Strict control over Titania levels during the fusion process ensures optimum toughness of the grains.

Once the brown fused alumina has been produced, it can be further processed and tailored to meet specific needs. For example, the material can be sintered to produce harder, more durable abrasives that are resistant to wear and tear. This sintering process involves heating the material to extremely high temperatures in a special furnace, causing it to bond together into a solid mass.

Another processing method involves grinding the material to a specific size and shape. This can be done using specialized grinding machines that use diamond or CBN wheels to achieve a high level of precision and accuracy. The resulting abrasive can be used for a variety of applications, including surface preparation, deburring, and smoothing.

Brown fused alumina is also used in a variety of industrial applications, including in the production of ceramic coatings, which are used to protect against wear and corrosion in various industries. In addition, it is used as a component in refractory materials, such as ceramic fiber insulation and bricks, which are used in high-temperature applications such as cement production and power generation.

Furthermore, brown fused alumina is also used in the manufacturing of semiconductor devices, such as computer chips and transistors. The material's high purity and low defect density make it ideal for use as a support material in the production of semiconductor devices.

Another potential application of brown fused alumina is in the field of medical devices, such as catheters and stents. The material's biocompatibility and biodegradability make it a promising candidate for use in these devices.
