Abstract
Very dense zirconia-toughened ceramics with a mullite matrix based on the quaternary system ZrO2-Al2O3-SiO2-TiO2 in the temperature range 1450 to 1550° C have been obtained by reaction sintering of zircon/alumina/titania mixtures. The reaction mechanism, advance of reaction, microstructure and mechanical properties of different compositions are reported. The results are explained in terms of a transitory liquid phase that appears at ~ 1400° C.
