摘 要：<正>An investigation of the pressureless sinteringof Si3N4 with MgO-CeO2 reveals that Mgo-CeO2 is a muchmore effective sintering aid for silicon nitride than eitherMgO or CeO2.The amount of MgO-CeO2 and MgO/CeO2weight ratio has a strong influence on the densification be-haviour and mechanical properties of the sintered materials.The Silicon nitride pressureless sintered with MgO-CeO2 re-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.
