Low temperature degradation free Zirconia toughened alumina (ZTA) has been developed. It is reported that ZTA has higher mechanical strength compared to alumina due to the stress induced transformation and spontaneously transformation of zirconia phase on some ZTA have been occurred. For achieving the higher reliability of artificial joint prosthesis alternative to alumina and other ceramic materials, it is necessary to improve and validate the both mechanical characteristics and phase stability at the same time. We evaluated that microstructure, mechanical characteristics and phase stability of newly developed ZTA (BIOCERAM®AZUL). It was confirmed that four-point bending strength and weibull modulus were extreamly high, and ZTA has higher reliability. There were no significant changes and deterioration in four-point bending strength, crystal structure and wear property with and without accelerated aging test. Newly developed ZTA not only with high mechanical characteristics but also with phase stability could be quite useful as bearing materials in artificial joints for longer clinical use.

Based on the electrophysical and structural data, a crystallophysical model of the ionic transport in superionic conductors Ba1-xLaxF2+x and Ca1-xYxF2+x (space group Fm¯3m), in which the charge carriers are mobile interstitial ions F− resulting from heterovalent substitutions of fluorite fragments of [M14F64] (M = Ca, Ba) by structural clusters of [M8R6F69] (R = La, Y). Single crystals of Ca1-xYxF2+x (0.02<x<0.16) and Ba1-xLaxF2+x (x = 0.31) solid solutions were obtained by directed crystallization of the melt. The mobility of ionic carriers in isostructural superionics Ba0.69La0.31F2.31, Ca0.84Y0.16F2.16, Pb0.67Cd0.33F2, and Pb0.9Sc0.1F2.1 are compared. Crystals of Ba1-xLaxF2+x and Ca1−xYxF2+x with improved conductometric and mechanical characteristics are promising active to replace the traditional CaF2 electrolyte in galvanic cells for thermodynamic research of chemicals.
