摘要：

An investigation of the pressureless sinteringof SiNwith MgO-CeOreveals that Mgo-CeOis a muchmore effective sintering aid for silicon nitride than eitherMgO or CeO.The amount of MgO-CeOand MgO/CeOweight ratio has a strong influence on the densification be-haviour and mechanical properties of the sintered materials.The Silicon nitride pressureless sintered with MgO-CeOre-tains a relative density of 98.5%,a bending strength of 950MPa.The Si-Mg-Ce-O-N system is of great value for appli-cation and theoretical study.
