Superhard ceramics

Article Abstract:

Zerr and colleagues have found a new cubic compound in silicon nitride. Silicon nitride is of interest in the ceramics industry due to its potential as a material for high-temperature heat engines. The cubic silicon nitride has a more dense and stiff structure, and may be as hard as stishovite. The higher density spinel structure is due to high pressures during fabrication.

Sintering dense nanocrystalline ceramics without final-stage grain growth

Article Abstract:

Sintering eliminates interparticle pores in a granular material by atomic diffusion driven by capillary forces, and is used in manufacturing industrial ceramics. It is shown that fully dense cubic Y(sub2)O(sub3) with grain size of 60 nm, can be prepared using a two-stage sintering method at temperatures of around 1,000 degrees C, without the application of pressure.

A high-strain-rate superplastic ceramic

Article Abstract:

Research is presented concerning the exhibition of superplasticity of a composite ceramic material which consists of magnesium aluminate spinel, alpha-alumina and zirconium oxide phases at a strain rate of up to 1 s-1.
