Изобретение может быть использовано при изготовлении керамики, катализаторов, сорбентов. Осаждают гидроксид циркония, затем его сушку и прокаливание проводят одновременно под действием СВЧ-излучения в частотном диапазоне 500-20000 МГц с непрерывной мощностью 3,0-50,0 кВт в течение 5-60 мин. Изобретение позволяет снизить агрегацию нанопорошков диоксида циркония и получать порошки с удельной поверхностью до 39,8 м2/г, 2 ил., 1 табл. |
