Pressureless sintering and elastic constants of Al2O3-SiC 'nanocomposites'

Abstract:

A study is presented of how to obtain very near theoretical densities (≥99-6%) in Al2O3-SiC 'nanocomposites' by pressureless sintering. Several factors are considered in order to achieve the optimal densification. The most important factors are: good dispersion of SiC particles in the matrix, cold-isostatic pressing of green samples and use of a relatively coarse-sized bedding powder (which allows efficient effusion of carbon monoxide from the sample), correct choice of sintering temperature ...
