General features of silicon nitride based ceramics, which may well influence their creep
behavior are presented. Then, the most commonly invoked models for the microscopic …

Silicon nitride (Si3N4) based ceramics are gaining more and more attention due to their
promising high-temperature thermal and mechanical properties. They have been expected …

The aim of this study was to evaluate the mechanical properties and coloration of silicon
nitride ceramics in the presence of RE 2 O 3 (RE= Nd, Eu or Dy). Dense Si 3 N 4 ceramics …

I attempt an overview of the nature of interatomic forces in materials based on the ideas of
density functional theory and the variational principle, without details of the mathematics …

The fabrication and properties of electrically conductive Si3N4–MoSi2 composites using two
different sintering additive systems were investigated (i) Y2O3–Al2O3 and (ii) Lu2O3. It was …

Wettability is the most important phenomenon in SiC liquid phase sintering. This paper
discusses the ceramic–ceramic wetting of E2O3/Al2O3 additives on SiC, where E2O3 is a …

α-SiAlONs are commonly produced by liquid phase sintering of Si3N4 with AlN and Y2O3 as
additives. The formation of the α-SiAlONs using a mixed oxide (RE2O3), containing yttria …

In this study, α-and α/β-SiAlON materials, doped with Y2O3 and Nd2O3, were sintered using
two different sintering processes: spark plasma sintering (SPS) and gas pressure sintering …

This work analysed the effect of the addition of rare-earth mixed oxide (RE 2 O 3), a solid
solution of Y 2 O 3 and other rare earths benefited from a Brazilian natural ore called …

The influence of additive content on the microstructure and its mechanical properties in
planes parallel and normal to the hot-pressing axis of Si3N4 ceramics has been investigated …
