Silicon carbide ceramics were prepared with SiC powder treated by the fluidized bed opposed jet mill as raw materials, and the effects of the ultra-fine treatment mechanism on the compaction and sintering behavior of SiC ceramics were investigated. The results showed that the compacts had higher density and microstructure homogeneity when the sintering temperature of the compact was decreased
Silicon Carbide Structure – SiC Bonding in Silicon Carbide – SiC Silicon carbide crystallizes in a close packed structure covalently bonded to each other. The atoms are arranged so that two primary coordination tetrahedral where four carbon and four silicon atoms are bonded to a central Si and C atoms are formed.These tetrahedra are linked together through their corners and stacked to form
