Transparent polycrystalline ceramics have found various applications, such as laser hosts,
infrared (IR) windows/domes, lamp envelopes and transparent armors, instead of their …

(Oxy) nitride materials, consisting mainly of transition metal and ionic‐covalent (oxy) nitrides,
show a vast number of interesting physical and chemical properties due to their substantial …

The history of inorganic luminescent materials (phosphors) dates back to the time when the
first phosphor, barium sulfide, was produced in the nineteenth century. Since then …

Abstract A 2 B 2 O 7 system compounds, which usually present three phase structures
mainly based on the ionic radius ratios of r A and r B (r A/r B), have been studied for potential …

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 …

With the development of hypersonic vehicle technology, ceramic-based radome materials
are highly demanded due to their high operating temperatures, good dielectric properties …

SiC whiskers (SiC w)-reinforced α/β-SiAlON ceramic tool materials were synthesized via
spark plasma sintering (SPS). A comprehensive study was conducted on densification …

Cerium‐doped α‐SiAlON (MxSi12−(m+ n) Alm+ nOnN16–n) materials have been prepared
by gas‐pressure sintering and post‐hot‐isostatic‐press (HIP) annealing, using four powder …

Silicon nitride for engineering applications is densified by liquid phase sintering using oxide
additives such as yttria and alumina. The oxynitride liquid remains as an intergranular glass …

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 …
