Физико-механические свойства циркониевой керамики для остеозамещения

Abstract

In this work, porous ceramic materials based on zirconium dioxide have been studied. Ceramics are obtained by uniaxial cold pressing of powder mixtures followed by multi-stage high-temperature sintering at 1500°C. Spherical ultrahigh molecular weight polyethylene (UHMWPE) with an average particle size of about 150 µm was used as a blowing agent. The following data were obtained: pore size distribution, flexural strength, modulus of elasticity, and the viability of a 3T3 mouse fibroblast cell culture was studied. The data indicate that the mechanical parameters of the obtained material correspond to those of the bone tissue. The studied ceramics showed high biocompatibility.
