The role of phase diagrams of refractory oxide systems in a microstructure design of oxide composites is presented. The importance of scientifically grounded approach to each stage of the materials fabrication from the synthesis of initial powders to the sintering is shown in order to create the optimal structure and to ensure the high level of the physical and mechanical properties of high-tech ceramic materials in the ZrO2?Y2O3?CeO2?Al2O3–ÑîÎ system. The variation of the hydrothermal synthesis conditions (acidic/alkaline medium) and the using of combined method for the initial nanocrystalline powders’ synthesis at constant chemical composition of the system allow to change the phase composition of composites in a wide temperature range and to create oxide composites with various microstructure and predefined properties.
