This paper presents the results of macro- and microstrength studying in ceramic composite materials ZrO2-MgO with 50% porosity. Pores had a bimodal structure with average sizes about 28 and 103 microns. It was shown that the material strength is mainly determined by grain boundaries stresses and reduce with increasing of the second type stress.
