摘要：

The influence of the conditions of hot isostatic pressing (HIP) on the mechanical properties of presintered ceramics containing 94, 97, and 99% Al2O3 is studied. It is shown that HIP treatment provides the possibility of increasing substantially the strength, the crack resistance, and especially the modulus of the Weibull function for the statistical strength distribution. The optimum HIP parameters depend on the composition and previous technological history of the ceramics.
