Приведены результаты исследования структуры и радиофизических свойств в диапазоне частот 8 12 ГГц композиционных материалов, приготовленных из природного ильменита, и алюмооксидной керамики с различным содержанием примесей. Рентгеноструктурный анализ показал, что в обоих случаях преобладает структурный тип корунда. Обнаруженный эффект сильного влияния примесей на радиофизические характеристики позволяет синтезировать как радиопрозрачные, так и радиопоглощающие материалы с одинаковой кристаллической структурой.
Research results of the crystal structures and radiophysical properties at frequency range 8 12 GHz of compositional materials prepared from natural ilmenite and oxide aluminum ceramics with different admixtures are given. X-ray crystal analysis showed that structural type of corundum is predominated in both cases. Strong influence of admixtures on radiophysical properties is discovered that allows to synthesize radiolucent as well as radioabsorptional materials with identical crystal structure.
