The Zirconia Ceramic Strengths and Weaknesses

2014418 CHIPPING AND FAILURES Chipping is defined as a typical failure of contact loadings normally produced when a crack generated or propagated by contact loads deflects due to the presence of a free surface nearby 64 65Tensile stress induces fracture of the brittle ceramic usually perpendicular to the applied force Thermal coefficient mismatches

Zirconia in Ceramic Materials

2021723 Zirconia which has monoclinic crystal structure at room temperature has ability to transform its structure from tetragonal to monoclinic as temperature changes or the stress increases Apart from this property another important point to know is that when zirconia is mixed with other oxides its cubic/tetragonal phases become stabilised
