Resin-bonded superabrasives are grinding tools made mainly from artificial diamond or cubic boron nitride as the main raw materials. In addition to superabrasive materials, filling materials are often added to superhard grinding tools to achieve reinforcement, increase porosity, and reduce costs. Green SiC powder, as a filling material for superhard grinding tools, has the following functions and advantages:
Reshaped Green silicon carbide 100 # grit is processed by special crushing and sand-making processes. The bulk density is higher than ordinary green silicon carbide grain with more round particles. When producing silicon carbide ceramic parts, adding more silicon carbide to the same container is beneficial for improving the density and mechanical strength of bulletproof ceramics. The difference between the two is shown in the following figure:
In the field of new building materials, the development trend of foam glass insulation is rapid. The other name of foam glass is ceramic sponge. As an external wall insulation material, it has the characteristics of good insulation effect, flame retardancy, non-deformation, and long service life. Green SiC powder is a popular ceramic material, and green SiC 10000# is an alpha-phase green silicon carbide powder with a SiC purity of over 98%. Its particle size range is between 0.3um and 2.5um, with a median particle size of 0.6-0.8um in D50. This ultra-fine SiC powder is not only a finely ground polishing powder but can also be added to composite materials to improve their physical properties.
Silicon carbide powder is a high-hardness non-metallic abrasive product. It is second only to diamond in hardness in synthetic materials. There are few silicon carbide materials in the natural minerals. In the meantime, the use in the industrial field covers a large range. Silicon carbide is an important industry related to the national economy and people’s livelihood. Therefore, smelting production through the Acheson process is an inevitable choice for the production of silicon carbide abrasives. However, the production industry and equipment of silicon carbide are complex and consume a large amount of electricity. Chinese silicon carbide abrasive manufacturers have explored step by step, and currently, China’s silicon carbide abrasive production capacity accounts for over 80% of the world’s.
GC Abrasive Powder refers to green carborundum powder with a grit size of 240mesh -10000 mesh. It is a popular grinding material, ceramic raw material, and wear-resistant material. Green silicon carbide is a special material obtained by high-temperature smelting of petroleum coke, silica sand, and coke with wood chips and table salt. GC Abrasive powder is a fine particle obtained by crushing, grinding, acid washing, overflow grading, and drying large blocks of green silicon carbide.
Due to its excellent characteristics, it works excellently in applications such as national defense, aerospace, electronics, chemical metallurgy, and automobiles.
Green silicon carbide is not only a good grinding material, but also suitable in the metallurgical industry and refractory materials field. The silicon carbide content of green silicon carbide is higher than that of black silicon carbide. In the meantime, its hardness and wear resistance are much higher than that of black silicon carbide. The main applications of green silicon carbide in the metallurgical industry are as follows
