The main analytical test methods silicon carbide powder:

The main purpose
For H&X garnet abrasive inch monocrystalline silicon, polycrystalline silicon, gallium arsenide, wire-cut quartz crystal. Processing materials are engineered solar photovoltaic industry, the semiconductor industry, piezoelectric crystal industry.
The main analysis of silicon carbide detection methods:
Determine the content of silicon carbide in the silicon carbide hardness. SiC particle size on the line cutting a great impact, but the most important thing is the shape of the silicon carbide particles. Because when H&X Aluminium hydroxide wire cutting silicon carbide particles to change the shape of the free state of cutting efficiency and cutting quality to be an important influence.
Detection methods: silicon content requires atomic absorption detection (high detection efficiency, more accurate values​​).
Silicon carbide particle resistance method requires particle analyzer (high efficiency).
Silicon carbide grain type detection requires Reith RA200 particle analyzer. (Particle shape can be analyzed more accurate roundness factor)

The crystal structure of silicon carbide powder

Feature
Green, crystal H&X white fused alumina suppliers, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity. Microscopic shape of a hexagonal crystal, silicon carbide 9.2 Mohs hardness, Vickers hardness of 3000 - 3300 kg / mm 2, a Knoop hardness of 2670-2815 kg / mm, hardness 3300 kg per cubic millimeter. Higher than corundum abrasives and second only to diamond, cubic boron nitride and boron carbide. Density is generally considered to be H&X garnet 80 mesh g / mm 3, the bulk density of silicon carbide abrasive nature of the 1.2 - between 1.6 g / mm 3, a specific gravity of 3.20 to 3.25. Green silicon carbide based petroleum coke and quality silica as the main raw material, add salt as an additive, smelting electric arc furnace. Hardness between corundum and diamond, corundum higher mechanical strength.

Black silicon carbide features and other purposes

Since silicon carbide chemical stability, high thermal conductivity,H&X carbide silicon expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses, such as: a special process the silicon carbide powder coating on the turbine impeller or cylinder body wall, can improve the wear resistance and extend the life of 1 to 2 times; for advanced refractory material, heat shock, small size, light in weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) is an excellent deoxidizer, with its speed steel to accelerate and facilitate control of the chemical H&X pink fused aluminium oxide, to improve the quality of steel. In addition, silicon carbide heating element is also used extensively for the production of silicon carbide.
The great hardness of silicon carbide having excellent thermal conductivity, is a semiconductor, resistant to oxidation at high temperatures.
