Creep and Structure of Ceramics

Inorganic Materials Aims and scope

Abstract

The effects of pores and low-melting phases on the creep in multiphase oxide ceramics are analyzed using experimental data. It is shown that the high stress level produced by pores has no effect on the creep behavior of the ceramics. The pores reduce the contact cross section, which is smaller than the effective cross section taking into account only the pore area. The deformation of the skeleton is determined by the content and viscosity of the low-melting phase, whose composition and distribution depend on the content of impurities. The grains of the refractory phase increase the effective viscosity of the material.
