pls see details at website:http://xxxxx The beta modification of silicon carbide, β-SiC with a face centered cubic crystal structure (similar to diamonds) provides the micro-particles better natural sphericity compared to α-SiC which has a hexagonal crystal structure (similar to Wurtzite). Therefore, it exhibits a better grinding and polishing effect in precision grinding. outstanding characteristic of dense packing during the manufacturing material process, sealing products and defence industry products, provide these products with a higher density than the traditional alternatives. Because the manufacturing temperature of β-SiC powder is much lower than that of α-SiC. it can be easier to refine in a uniform way. Moreover, it can produce extremely superfine powder particles within the range of nanometer to the submicron level. It is also easier to obtain amorphous β-SiC powders by controlling the processing parameters. All of these provide β-SiC powders with much more outstanding sintering activity than α-SiC powders. Therefore, it can be realized by sintering and densifying various products under lower temperatures using a cheaper sintering facility and with simpler technological processes in order to obtain the required kinds of structural materials with good mechanical performance. This makes it a promising source of manufacturing structural material with a high price-performance ratio. 　　Because β-SiC has better electrical performance and it is easier to acquire purified products than with α-SiC, it has unique merits in the application field of electrical and electronic materials, especially in semiconductor xxxxx, β-SiC is getting wider acceptance in the electronic materials industry.
