Description

The object of study - nanostructured ceramics. The objective of the research is to develop methods for obtaining consolidated metal ceramic materials based on Y-Ti-Zr-O nano-size powders, as well as to establish correlation among their structural characte-ristics and physical and mechanical properties. Samples of compacted and consolidated ceramics with varying contents of Y2О3, TiО2 and ZrO2 oxides have been obtained. High-temperature impact technology for improving mechanical properties has been optimized. To control processes initiating structural changes, special technological techniques have been tested. It has been registered that an increase of the sintering temperature results in an increase of the average grain size. The outcomes of the research show that structures with a high degree of thermodynamic stability and a high level of mechanical properties have been implemented in ceramics.
