Silicon Carbide: Synthesis and Properties

摘要: Silicon carbide is an important non-oxide ceramic which has diverse industrial applications. In fact, it exclusive properties such as high hardness and strength, chemical thermal stability, melting point, oxidation resistance, erosion etc. All of these qualities make SiC a perfect candidate for power, temperature electronic devices well abrasion cutting Quite lot works were reported on synthesis since the manufacturing process initiated by Acheson in 1892. this chapter, brief summary given different crystal structures most common encountered polytypes will be cited. We focus then various fabrication routes starting from traditional led to large extent into commercialization silicon carbide. This based conventional carbothermal reduction method powders. Nevertheless, involves numerous steps, excessive demand energy provides rather poor quality materials. Several alternative methods have been previously production. An overview used elaboration physical vapour deposition (PVT), (CVD), sol-gel, liquid phase sintering (LPS) or mechanical alloying (MA) detailed. The resulting mechanical, structural electrical fabricated discussed function methods.
