'Ultra' High-Temperature Microwave Sintering,

Abstract

'Ultra' high-temperature microwave processing, utilizing temperatures over 1900 deg C, is addressed. Primary areas of concentration involve titanium diboride (TiB2 - 3 wt% CrB2) and boron carbide (B4C -2.5 wt% C). Using 2.45 GHz radiation, high-density, crack-free specimens can be produced. The importance of 'casketing' and coverings along with material interactions is discussed. Comparison of microwaving with conventional sintering or hot-pressing indicates that microwaving may be advantageous.
