Методом ИК-спектроскопии изучены структурные отклики частиц монтмориллонитовой и каолинитовой глин месторождений Оренбургской области на СВЧ-воздействие. Обработку проб в течение 10 минут проводили в поле магнетрона мощностью 750 Вт в воздушной и влажной средах. Спектры получены с помощью ИК-Фурье спектрометра в диапазоне длин волн 4000–400 cм-1. Установлено, что в монтмориллонитовой глине количество доминирующих связей в тетраэдре SiO4 снижается в 1.5 раза при обработке в сухом воздухе и в 1.8 раза – во влажном. В глине, содержащей каолинит, все типы связей активно разрушаются под воздействием СВЧ-поля.
