      <abstract xml:lang="ru">
        <p>Тройная система ZrO₂–MgO–Al₂O₃ в целом до сих пор не была исследована. Литературные данные имеются лишь по двойным системам, ограничивающим стороны этой тройной системыроизведено исследование температур плавкости по трем разрезам в тройной системе ZrO₂–MgO–Al₂O₃ и найдено, что по направлению от ZrO2 к химическому соединению MgO–Al₂O₃ проходит непрерывная область твердых растворов, температура плавления которых повышается в зависимости от содержания ZrO2 от 2130° (шпинель) до 2715° (ZrO2). Отсутствие эвтектики, вызывающей преждевременное размягчение материала, делает эти смеси весьма важными высокоогнеупорными.</p>

      <abstract xml:lang="en">
        <p>The ternary system ZrO₂–MgO–Al₂O₃ as a whole has not yet been studied. Literature data are available only for the binary systems that form the sides of this ternary system. A study of melting temperatures was carried out along three sections in the ternary system ZrO₂–MgO–Al₂O₃, and it was found that in the direction from ZrO₂ to the chemical compound MgO·Al₂O₃, there exists a continuous region of solid solutions whose melting point increases with increasing ZrO₂ content from 2130°C (spinel) to 2715°C (ZrO₂). The absence of a eutectic, which would cause premature softening of the material, makes these mixtures very important as highly refractory materials.</p>
