Abstract

Porous ceramic ZrO2-MgO composite in a wide range of component content was studied. The effect of content and sintering parameters on pores size, its distribution, lattice structure, coherently diffracting domains and lattice microdistortion, tensile strength was investigated. It has been shown that the adding of pore-forming particles into the initial powder makes it possible to obtain a bimodal pore structure of composites. Sintering time and MgO content in ceramics are stipulated a changing of the average size of macro- and micropores and microstresses, which determine the macroscopic strength of the material.
