| description | Today, one of the most promising materials for a wide range of practical applications is lithium-containing ceramics based on Li<sub>2</sub>TiO<sub>3</sub>. At the same time, despite the high potential of their practical application, a number of questions remains related to the methods of their preparation, as well as the formation of a stable crystal structure and a pure-phase composition. To solve these issues, this paper proposes a method for obtaining stable Li<sub>2</sub>TiO<sub>3</sub> ceramics, which is based on solid-phase synthesis combined with the high-temperature sintering of ceramics. During the studies carried out using X-ray diffraction methods, temperature dependences of phase transformations of the TiO<sub>2</sub>/Li<sub>2</sub>Ti<sub>6</sub>O<sub>13</sub> → Li<sub>2</sub>TiO<sub>3</sub> type were determined, according to which, at temperatures above 800 °C, the formation of a stable Li<sub>2</sub>TiO<sub>3</sub> phase characterized by a high structural ordering degree of 89–91% is observed. The dependence of changes in structural, optical and ferroelectric characteristics on the conditions of synthesis and phase composition of ceramics was also determined. |
