Brown Fused Alumia powders are fused wIth premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown Fused Alumia is offered in macro and micro powder form, in both F and P grades.
Brown fused alumina for refractory
brown corundum is called industrial teeth: mainly used in refractory raw materials, grinding wheels, sand blasting.
Sandblasted brown corundum – sandblasted abrasive with moderate hardness, high bulk density, no free silica, large specific gravity and good toughness. It is an ideal “environmentally friendly” sandblasting material widely used in aluminum profiles and copper profiles. Washed denim clothing precision molds and other fields;
Free grinding - grinding grade abrasives, used in the fields of picture tube, optical glass, monocrystalline silicon, lens, glass for clocks, crystal glass, jade and other fields, is a high-grade abrasive material commonly used in China;
Resin Abrasives—Abrasives have suitable color, good hardness, toughness, suitable particle cross-section type and edge retention. They are used in resin abrasives with good results.
Coated abrasives—abrasives are raw materials for the production of sandpaper, gauze, etc.
Brown corundum functional filler - mainly used for automobile brake parts, special tires, special construction products, etc. It can be used as a wear-resistant material for highway pavement, airstrip, dock, parking lot, industrial floor, sports ground, etc.
Filter media – it is a new application field of abrasives. It uses granular abrasive as the bottom media of filter bed to purify drinking water or waste water. It is a new type of water filtration material at home and abroad, especially suitable for non-ferrous metal beneficiation and oil drilling mud weighting agent.

White corundum is made from industrial alumina powder, which is smelted in an arc at a high temperature above 2000 ℃ and then cooled. After crushing and shaping, magnetic separation to remove iron, it is divided into various particle sizes.
Brown corundum is made of natural bauxite as raw material, carbon (mainly coke) is used as reducing agent, and iron filings are added as sedimentation agent (clarifier) to form ferrosilicon deposited on the bottom of electric furnace.
The refractoriness of clay bricks is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. Because in addition to the high refractory mullite crystal, the clay brick also contains nearly half of the low melting point amorphous glass phase.
Refractory castable is a kind of refractory material that does not need to be formed and has good fluidity after being fired and stirred with water.
High alumina refractory bricks are the backbone of high-temperature industrial processes. By understanding their properties, applications, and supplier selection criteria, businesses can enhance operational efficiency and reduce downtime. For industries seeking durable, cost-effective solutions, partnering with certified refractory materials suppliers in China ensures access to cutting-edge technology and reliable supply chains.
Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.
The alkali-resistant brick for cement kiln has the characteristics of strong alkali erosion resistance, good thermal shock resistance and high cost performance.
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
