Получение и свойства керамических материалов на основе системы Al[2]O[3]-MgO

Abstract

It is known that aluminum oxide is the most generally used ceramic material applied as structural, functional and biomaterial. Meanwhile, it is used not only in a high state and but also in a highporous state. To obtain the required functional properties it is alloyed by various oxides such as FeO, SiO[2], Y[2]O[3], MgO and others. What most interested us is the magnasium oxide (MgO), as it is well known that the MgO presence in the ceramics materials causes biological processes activation at the boundary "implant - bone". However, the introduction of MgO into sintered mixture may change technological regimes of ceramics production and as a result to the structure and properties of the material can be changed as well. The aim of this work is to study the influence of the concentration of the injected mixture into the sintered MgO in the amount up to 10 wt. %. onto porosity, shrinkage characteristics of the microstructure and mechanical properties of the sintered material.
