High Temperature Material Properties of Ceramic Particle Composite

High Temperature Microwave Dielectric Properties of Ceramic Nano and Micropowders

The problem of microwave enhanced mass transport in solids remains an area of great interest and continued research in the microwave processing of materials. Many researchers have reported that microwave sintering of materials reduces the time and often the temperature of the sintering procedure [1]. The mechanisms of the mass transport enhancement phenomenon by microwaves termed “Microwave Eff...

Sintering properties of zirconia-based ceramic composite

This study examines the effects of different ZrB2 content on various mechanical properties and electrical conductivity of ZrB2/Y-TZP composite. Composites with ZrB2 content of up to 20 wt-% were particularly beneficial at the lower sintering temperature range by achieving greater densification and better hardness than Y-TZP monolith. In contrast to the trends estimated from rule of mixture, the...

Ceramic Membranes and Thin Films High-Temperature Catalyst Supports and Ceramic Membranes: Metastability and Particle Packing

Parameters and/or processes responsible for the stability of catalyst supports and ceramic membranes are discussed. Two major parameters/processes were identified which are responsible for the stabiliv of sol-gel derived nanostmctured oxides at elevated temperatures. They are metastable-to-stable phase transformation and structure and packing of primary particles within the aggregate. Based on ...

Tungsten material properties at high temperature and high stress

Recently reported results on the behaviour of the tungsten under conditions expected in the Neutrino Factory target have strengthened the case for a solid target option for the Neutrino Factory. This paper gives a description of the measurements of the surface motion of tungsten wires, stressed by a pulsed current, using a Laser Doppler Vibrometer in order to measure tungsten properties at high...
