Измерение температурной зависимости начальной проницаемости было использовано для изучения особенностей фазовых и структурных превращений в литий-титановых ферритах в зависимости от времени, скоростей нагрева и охлаждения, а также температуры жидкофазного спекания при термическом и радиационно-термическом нагреве. Феррит синтезировали из порошковой смеси методом твердофазного синтеза. Для получения ферритовой керамики методом жидкофазного спекания использовалась легкоплавкая добавка диоксид висмута. КС-спекание осуществлялось при нагреве образцов импульсным (1,5–2,0) МэВ электронным пучком. Радиационно-термическое спекание осуществляли путем нагрева образцов импульсным электронным пучком (1.5–2.0) МэВ. Было установлено, что добавка приводит к менее дефектному состоянию спеченных ферритов, в то время как действие излучения усиливает этот эффект на ранних стадиях спекания. Установлены закономерности влияния скоростей нагрева и охлаждения спрессованных образцов на изменение начальной магнитной проницаемости спеченных ферритов.
