Abstract
Fully dense zirconia toughened ceramics with a mullite matrix from the basis of information on the quaternary system ZrO2-Al2O3-SiO2-CaO, in a temperature range as low as 1425 to 1450° C, have been obtained by reaction sintering of zircon/alumina/calcium carbonate mixtures. The shrinkage, 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 temperatures lower than 1400° C.
