Densification mechanism and microstructural evolution of Si3N4 composites with CeO2 as additives during spark plasma sintering
The densification mechanism of CeO _2 doped Si _3 N _4 ceramics during spark plasma sintering (SPS) was investigated. The sintering process was observed to undergo significant densification at the intermediate stage of sintering (1435 °C–1816 °C), and the density and grain size of CeO _2 doped Si _3...
