Aluminum oxide and applications

brown fused aluminaBrown fused alumina (BFA) is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc furnace and become, use it made of abrasive, suitable for grinding the high tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced refractories.Brown fused alumina has high purity, good crystallization, high fluidity, low linear expansion coefficient and corrosion resistance.Through the practice of dozens of refractory production enterprises, the product has the characteristics of non-detonation, pulverization and non-cracking in the application process.In particular, it is far higher than the traditional brown corundum, which makes it the best aggregate and filling material for the refractory materials.


The main ingredient of brown alumina is alumina, and the grade is divided by the aluminum content. The lower the aluminum content is, the lower the hardness is.


Product granularity according to international standard and national standard production, can be processed according to the requirements of users.The general particle size is F4~F320, and its chemical composition is different depending on the size of the particle.The prominent feature is the small impact of the crystal size, because the grinding machine is used to process the crushing, the particles are mostly spherical particles, the surface is dry and clean, and it is easy to combine with the agent.


Brown fused aluminum is the tooth of industry: mainly used in refractory materials, grinding wheel, sandblasting.

1. Used for making high grade refractory materials, pouring materials, refractory bricks, etc.

2, sandblasting abrasive hardness is moderate, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields;

3, free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, glass, crystal glass lens, clock, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials;

4. Resin grinding tools -- abrasive with suitable color, good hardness, toughness, suitable particle section type and cutting edge retention, applied to resin grinding tools, ideal effect;aluminum oxide

5. Coated abrasives - abrasive is the raw material for the manufacturers of sandpaper and gauze;

6, functional filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement. The runways. Dock. The parking lot. Industrial floor. Sports venues such as wear-resistant materials;

7, filter medium, is a new kind of application field, abrasive using granular grinding for the bottom of the medium filter bed, purify drinking water or wastewater, is a new type of water filtration materials at home and abroad, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent:

8, hydraulic cutting - an abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipe, steel components, such as cutting, is a new type, environmental protection, safe way of cutting.
