Product Introduction: Black Silicon carbide is made by using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting. There is also a rare mineral silicon carbide in nature--the Mo SangShi. Silicon carbide is also called the moissanite. In contemporary, among the oxide refractory raw material of high and new technology such as C,N,B, silicon carbide is the most widely used and one of the most economic materials. Features: 1.Small thermal expansion coefficient 2.Stable chemical performance 3.High hardness 4.Excellent wear resistance 5.Good heat conduction performance Applications: 1.Abrasive and grinding machine 2.Used for metallurgical steelmaking deoxidizer and high temperature materials 3.High purity single crystal,can be used for manufacturing a semiconductor,manufacturing a silicon carbide fiber White Fused Alumina

Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.
Brown fused alumina melt film precision casting sand is based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers requirement. The precision casting sand with high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.
Brown fused alumina is fused in the electric furnace with the high quality abrasive grade bauxite , coal and scrap iron as the raw material. Brown Fused Alumina for refractory is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion ,good corrosion-resistance and so on. In particular, its performance-cost ratio is much higher than traditional Brown Fused Alumina, making Brown Fused Alumina become the best aggregate and padding of brown fused alumina refractory materials.
White fused alumina for sandblasting abrasive utilized by unique advanced technology. It is characterized by short grinding time, high efficiency and so on. In particular, its advantages such as high hardness, good chemical stability and unique self-sharpening , it becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.
Introduction White Fused Alumina (WFA) is made from Calcined Alumina and is a friable product. Like Brown Fused Alumina, WFA is used in the manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting purpose and as polishing media and refractory grade WFA is used as raw material for high alumina refractories Application White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory material.
