"Исследования проводились на образцах литий замещенного феррита. Радиационно-термическое спекание осуществлялось облучением заготовок импульсным пучком электронов с энергией (1.5-2.0) МэВ, токе пучка в импульсе (0.5-0.9) А, длительности импульса облучения – 500 мкс, частоте следования импульсов – (5-50) Гц, скорости разогрева заготовок – 1000 °C/мин. Спекание в термопечах (Т-спекание) производилось в предварительно разогретой камерной электрической печи. В работе показана независимость магнитной индукции от зернистости феррита. При этом коэрцитивная сила обратно пропорциональна размеру зерна и зависит от внутризеренной пористости ферритовых образцов. Радиационно-термическое спекание, в отличие от термического спекания, не приводит к захвату межзеренных пустот растущими зернами и способствует коагуляции внутризеренных пор. "
