Abstract
This work reports the influence of porous ZrO2-MgO ceramic composition on its structure and mechanical properties. The bimodal pore structure were formed by introduction of organic pore forming particles into the initial powder composition and due to the voids between ceramic powder particles. It was shown, that the mechanical parameters of the porous ZrO2-MgO composite are substantially defined by the value of the microstresses, the MgO content, and, apparently, the formation of a percolation structure. Thus, it was shown that by varying the composition and the size of the pore-forming particles, it is possible to achieve a high degree of identity with the structure and properties of natural bone tissue.
