The main differences between green silicon carbide and black silicon carbide are raw materials, production process, physical and chemical properties, and application areas.
The functions and uses of green silicon carbide are very extensive, mainly including abrasives, refractory materials, functional ceramics, metallurgical mineral processing, electrical and chemical industries and other fields.
In today’s chemical industry, the chemical stability of materials is a crucial performance. Especially in the face of complex conditions such as high temperature, high pressure, and corrosive environment, whether the material can maintain its stable properties is directly related to the efficiency of industrial production and the quality of the product. Zirconia, as an important inorganic non-metallic material, has a wide range of applications in many fields due to its unique physical and chemical properties. This article will focus on the chemical stability of zirconium oxide and its importance in the chemical industry.
Brown fused alumina is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products.
These grains are also used for shot blasting and as polishing media.
Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory..
White Fused alumina (WFA）was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.
It is white with the main crystal phase α-Al2O3.
The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
