This paper deals with the densification and phase transformation of Si3N4 with additives of Li-exchanged zeolite during pressureless sintering at significantly reduced temperatures. Dilatometric shrinkage data show that ...

The influence of the sintering additive LiYO(2) (5-15 wt.%) on sintering behavior, microstructure and mechanical properties of Si(3)N(4) ceramics was investigated. Since LiYO(2) enables densification of Si(3)N(4) at ...
