Factors to Consider When Selecting and Using White Fused Alumina Grit
Green silicon carbide powder is a kind of high purity silicon carbide grinding powder. It is made from petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and smelted at high temperature through a resistance furnace. This article will briefly introduce green silicon carbide powder.
Green silicon carbide powder is green in color, crystal structure, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity. It is higher than corundum and second only to diamond, cubic boron nitride and boron carbide in abrasives. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, through the resistance furnace high temperature smelting. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.
Thermal conductivity: Green silicon carbide powder products have very high thermal conductivity and thermal shock resistance, and a small thermal expansion parameter, it is a high-quality refractory material.
Density: The particle density of various green silicon carbide powder crystal shape is very close. The common feeling is 3.20 g/mm³, and its abrasive course stacking density is between 1.2--1.6 g/mm³. Its height lies in the particle size number, particle size synthesis, and particle shape.
Hardness: Green silicon carbide powder's Mohs' hardness is 9.2, Wechsler's microdensity hardness is 3,000---3,300 kg/mm², Nup hardness is 2,670-2,815 kg/mm², higher than corundum in the abrasive material and second only to diamond, cubic boron nitride and boron carbide.
It is used for wear-resistant, fire-resistant, and corrosion-resistant materials, and can also be used to make rocket nozzles and gas turbine blades. In addition, green silicon carbide is also one of the ideal materials for highways, airplanes runways solar water heaters, and so on.
Green silicon carbide powder is an ideal indirect material for ceramic glaze baking and sintering. Due to its thermal conductivity heat radiation and high heat intensity, using it to manufacture thin sheet kiln furniture improves the capacity of the kiln and the quality of the product, and shortens the production cycle.
Green silicon carbide hardness is second only to diamond, with strong wear resistance, is the wear-resistant pipeline, impeller pump room cyclone, the ideal material for the lining of the bucket. Its wear-resistant performance is cast iron, rubber life of 5 - 20 times, but also one of the ideal materials for aviation runway.
As a kind of high purity silicon carbide grinding powder, green silicon carbide powder plays a pivotal role in industrial production with its unique physical properties and wide range of applications. With the continuous progress of science and technology and the in-depth expansion of applications, the performance and use of green silicon carbide powder will be further improved and expanded, contributing more strength to the development of modern industry.
