| 摘 要： | INTRODUCTION In powder compaction, the characteristics ofthe powder affect the compaction behavior and thequality of the pressed green body and its relativedensity, porosity, pore size distribution, sinteringand the consequent microstructure of the final sin-tered body. Superfine powder is prerequisite forpreparing high performance ceramic materials (Liu,1996; Lange et al., 1983; Lange, 1989). At present,most of the chemosynthesis methods are not suit-able for preparing industrial …

| Abstract: | 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; and that the surface microstructure, densification and mechanical properties of the sintered body could be ameliorated obviously. |
