| Реферат: | eng: The Ti-Al-Zr-O system has received significant attention as it hosts a variety of phases of industrial interest. In this paper, new experiments on the Ti-Al-Zr-O system aimed at clarifying phase formation depending on the redox conditions with special attention to the formation of ternary compounds and their results have been reported. For the first time a monophase AlTi2O5 sample with a ratio of titanium oxides TiO2:Ti2O3 = 2:1 was obtained and characterized. Single-crystal X-ray diffraction analysis of β-(ZrxTi1-x)2O4 crystals was carried out. The synthesis of the ternary Ti-Al-Zr compound was performed in an evacuated quartz ampoule and accompanied by the extraction of silicon from the ampoule. The compound has pyrochlore-type cubic structure A2 4+B2 3+O7 (Fd-3m) and the composition close to (Ti4+ 1,47(2)Zr0.41(2)Si0.12(1))2(Al1.15(4)Ti3+ 0.85(4))2O7. We believe that our study is a starting point for future research as it provides first experimental data on the ternary compound in the Ti-Al-Zr-O system. © 2020 Elsevier Ltd
