For better control of the mechanical properties of Si3N4 ceramics, it is necessary to generate
homogeneous microstructures, and for this purpose, chemical heterogeneities must be …

A simple method of integrating a powder processing technique with a sol–gel process to
produce ultra high temperature ceramic (UHTC) composites is reported. ZrB 2 powder was …

Magnesium matrix composites reinforced by three dimensional (3-D) network structure were
fabricated by pressure-less infiltration technology. The 3-D network structure reinforcement …

In this study, the sintering behaviour of silicon nitride (Si3N4) powders (having in situ form
sintering aids/self-sintering additives) produced directly by the carbothermal reduction and …

Abstract Si 3 N 4/Al–Mg composites reinforced by ceramic interpenetrating network structure
had been fabricated via pressureless infiltration technology. The matrix and the …

This review examines the application and potential of silicon nitride ceramics in artificial joint
replacements. Silicon nitride offers a unique combination of mechanical strength, wear …

The high-temperature applications of zirconium diboride (ZrB 2) ceramics are hindered due
to their easy initial oxidation at temperature around 700° C. Although mixing and coating …

Cerâmicas à base de Si3N4 tem sido estudadas exaustivamente para aplicações
estruturais e como ferramentas de corte. As excelentes propriedades mecânicas deste …

Cerâmicas à base de Si3N4 têm sido exaustivamente estudadas nos últimos anos e a
adição de uma segunda fase formando um compósito é alvo de várias pesquisas. A …

Theoretical investigations on the ZrxTa1-xO1+ xN1-x system predict that some of its phases
are likely to possess relatively high hardness values.(1) Such materials may be suitable for …
