Abstract

Mechanical properties of ceramics obtained by the sintering of stabilized zirconia microspheres are investigated. Strength at compression and tension, elastic deformation and modulus of elasticity at compression, specific works of fracture, of fracture initiation, and stress intensity factor are determined. An expression is proposed to establish the dependence of strength on macrostructure parameters of brittle material sintered from microspheres, and its analysis is given.
