Abstract
Local differences in the density, grain size or chemical composition within a sintering compact can seriously limit the final densities which can be achieved. Experiments on zirconia-alumina composites have been conducted to test the influence of such variations. Experiments are described which measure the stresses produced in the sample as a consequence of local differences in the sintering rate, and which indicate variations in the accumulated density change occurring in the composites and in single-phase standards. An estimate is given for the acceptable degree of inhomogeneity if full density is to be achieved.
