Spark plasma sintering of alumina/yttria‐doped silicon carbide

Silicon carbide possesses exceptional mechanical and thermal properties, but its den-sifiion by conventional sintering is often very difficult. In the present work, sili-con carbide was consolidated by spark plasma sintering in the presence of alumina and yttria

GC#1500 Green Silicon Carbide ,silicon carbide …

Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in appliions requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof

Growth Mechanism of Cubic-Silicon Carbide Nanowires

Cubic-SiC nanowires were synthesized using activated carbon powder and Si substrate in vacuum at 1200–1350°C for 1–4 hours. The nanowires were grown according to the following proposed mechanisms: (1) diffusion of C/CO into Si substrate, (2) weakening of Si bond and atomic kick-out, (3) formation of Si-C in vapor phase, (4) formation of saturated SiC layer, (5) formation of pyramid-like
