Brown Fused Alumina Oxide Manufacturers In China

brown fused alumina is made of high-quality bauxite, anthracite, iron, smelted in an arc at a high temperature above 2000 degrees, smashed by a self-grinding machine, magnetically removed to remove iron, and sieved into a variety of particle sizes. The granules are spherical, suitable for manufacturing ceramics, resin high-consolidation abrasives, grinding, polishing, sandblasting, precision casting, etc., and can also be used for brown fused alumina suppliers manufacturing advanced refractory materials.

Application: white alumina has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient, and corrosion resistance. It has been verified by dozens of refractory production enterprises that this product has the characteristics of no explosion, no chalking and no cracking in the application process. In particular, its cost performance is much higher than that of traditional brown corundum, making it the best aggregate and filler for brown corundum refractories.


Its dense texture and high hardness. It has high purity, good self-sharpness, resistance to acid and alkali corrosion, brown aluminum oxide high temperature resistance, and stable thermal performance. The hardness of white alumina is slightly higher than that of brown alumina, with slightly lower toughness, high purity, good self-sharpening, strong grinding ability, small heat generation, aluminum oxide grit high efficiency, resistance to acid and alkali corrosion, and high temperature and thermal stability.


black corundum sand: 0-1mm 1-3mm 3-5mm 5-8mm Physical and chemical indicators: Al2O3 ≥ 99% Na2O ≤ 0.5% CaO ≤ 0.4% Magnetic material ≤ 0.003%. Brown corundum is based on bauxite, anthracite, and iron filings. It is smelted in an electric arc furnace at high temperature. It is tan, has good toughness, micro hardness 1800-2200Kg / mm2, silicon carbide abrasive bulk density ≥3.85g / cm3, High temperature and refractory up to 1850 ℃, it can be used as refractory and abrasive.


The immersion requirement is: 0.4g stearic acid, 20g grinding powder, and 200ml aviation gasoline, soak in a ground glass bottle for more than seven days. chrome corundum is alumina powder as the main raw material, suitable for chromium oxide, etc., and smelted at high temperature. It is pink in color, similar in hardness to green silicon carbide, and tougher than white alumina. The abrasive tool made with it has good durability and high grinding finish.


brown aluminium oxide is made of high-quality aluminum oxide powder. It is suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and sample grinding. Black corundum sand (also known as low-aluminum corundum sand, iron sand powder), a new type of polishing material. Three-water type and one-water type bauxite are used as aluminum oxide abrasive raw materials and processed by high temperature smelting and cooling of electric arc furnace.


White corundum is refined and crystallized by electrofusion. pink corundum are concentrated in basic materials, with strong cutting force, high toughness, rigidity and flexibility, and good wear resistance. High work efficiency. It is mainly used for sand blasting of stainless steel, metal products, optical glass, and bamboo and wood products. It is also a new type of black silicon carbide for manufacturing resin wheels, cutting blades, and abrasive cloth.
