Brown fused alumina (BFA) is a type of synthetic abrasive which is made by fusing bauxite, iron oxide and coke at high temperatures in an electric arc furnace. It has a brown color and is used for grinding, polishing, blasting and cutting applications.
BFA is known for its high hardness, toughness, and resistance to wear and corrosion. It is also chemically stable and does not react with acids or alkalis. These properties make it a popular abrasive for metalworking, surface preparation, and refractory applications.
BFA is available in a range of grit sizes and can be used for both wet and dry blasting. It is commonly used for cleaning and preparing surfaces for painting or coating, removing rust and scale, and shaping and finishing metal parts.
In addition to its abrasive properties, BFA is also used as a refractory material in the production of ceramics, glass, and cement. It is also used as a filler in plastics, rubber, and other composites.

Garnet sand is a good abrasive and a common replacement for silica sand in sand blasting. Alluvial garnet grains which are rounder are more suitable for such blasting treatments. Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets. For water jet cutting, garnet extracted from hard rock is suitable since it is more angular in form, therefore more efficient in cutting.

Sandblasting is a mechanical process with which the shallower part of a material is eroded through abrasion due to a pressurized abrasive jet. The most frequent application is metals surface cleaning, yet other possible uses include engraving of images on marble, stones and tiles.
Silicon Carbide(SiC) has become a promising material in semi-conductor industry, due to the development of SiC material manufacturing and the decrease of the cost in recent years.
Silicon Carbide (SiC) is a wide bandgap material and is the typical representative of the third-generation semiconductor materials. Due to the wide bandgap, high thermal conductivity, high saturated carrier mobility, high threshold breakdown electric field strength, and high chemical stability, it is an ideal substrate for the fabrication of power electronics and radio frequency devices operating at extreme environments, such as high temperature, high frequency, high power, and strong radiation. Therefore, SiC has extensive applications in white-light illumination, automobile electronic, radar communication, aeronautic and aerospace, and nuclear radiation.

Refractory ball are used by users as refractory ceramic balls. They are made of industrial alumina and refractory kaolin. They are scientifically formulated, formed and calcined at high temperature. The refractory balls are widely used in high and low temperature converters and reformers in fertilizer plants. The push-plate kiln ball acts to disperse the gas and liquid, and to support, cover and protect the catalyst. Refractory balls can also be used in steel mill hot blast stoves and heating converters.
Refractory ball are divided into two types, ordinary and high-alloy. The former is often used in converters and converters in industries such as sulfuric acid and fertilizers, while the latter is used in industries such as steel. The refractory ball has the advantages of high strength, wear resistance, small thermal conductivity, high efficiency and good chemical stability, and is not easy to be broken when the temperature is drastically changed. The service life is long, and the cleaning equipment is also convenient after use.
