Brown fused alumina is a fundamental abrasive product with excellent grinding properties. It is a brownish artificial corundum produced by melting and reducing bauxite, carbon materials, and iron filings in an electric arc furnace. Currently, it is widely used in industries such as refractory materials. What are its main applications?

Brown fused alumina has four main application fields, namely: functional ceramics, refractory materials, abrasives, and metallurgical raw materials.

1. As an abrasive, it can be used to make grinding tools, such as grinding wheels, oilstones, grinding heads, and sandstone-like products.

2. As a deoxidizer for metallurgy and high-temperature-resistant material.

3. High-purity single crystal, suitable for manufacturing semiconductor substrates and brown corundum fibers.

4. Due to its high hardness, excellent wear resistance, and high strength, it can be used in chemical systems as various reaction vessels and pipes, as well as components for chemical pumps. It is suitable for mechanical parts, various molds, such as wire drawing molds, pencil core extrusion die nozzles, and others; as cutting tools, mold abrasives, bulletproof materials, human joints, and sealing ring molds.

Primary Applications: Used for wire cutting of single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystals, etc., ranging from 3 to 12 inches. Engineering materials for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.

Covering fields such as semiconductor, lightning rod, circuit components, high-temperature applications, ultraviolet detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, fine wire high-temperature gauges, ceramic films, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear, and catalyst carriers.

In addition, brown fused aluminum oxide is widely used in the construction of furnace walls and roof linings for various high-temperature kilns. It is both heat-resistant and provides insulation, playing a crucial role in enhancing the production efficiency of kilns.
