This chapter reviews one of the important engineering ceramics developed over the last 40
years, silicon nitride and the related SiAlONs, a “family” of structural materials with high …

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 …

New interesting luminescent α-sialon (M (m/val+) val+ Si12-(m+ n) Al (m+ n) OnN (16−
n))(M= Ca, Y) materials doped with Ce, Tb, or Eu have been prepared and their …

Liquid-phase (LPS) sintered silicon carbide ceramics with additive systems containing
aluminium nitride and rare earth oxides in combination are candidate materials for good …

Oxidation resistance of a liquid-phase-sintered (LPS) silicon carbide (SiC) with Lu2O3–AlN
additive system was investigated in air between 1200 and 1500° C, for up to 100h. Oxidation …

The lack of thermal stability of some rare earth α-SiAlON phases has recently raised serious
doubts concerning the high temperature behaviour of such materials. As information on the …

Recent studies on rare earth densified α-sialon ceramics have shown that the resulting α-
sialon product, present either as a single phase or in conjunction with β-sialon, is unstable …

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 …

The yttrium–sialon ceramics with the composition of Y0. 333Si10Al2ON15 and an excess
addition of Y2O3 (2 or 5 wt%) were fabricated by hot isostatic press (HIP) sintering at 1800° …

Five different α-β sialon and α-sialon compositions have been prepared using different rare
earth oxide additives namely, neodymium, samarium, dysprosium and ytterbium. Post …
