Abstract

Изобретение относится к способу формирования металлооксидных частиц небольшого размера и содержит следующие этапы: a) подготовки исходного водного раствора, содержащего по меньшей мере один из иона металла и его комплексов при концентрации такого металла не меньше 0,1 мас.%; b) подготовки модифицирующего водного раствора при температуре выше 50°С; c) контакта модифицирующего раствора с исходным водным раствором в непрерывном режиме в смесительной камере для формирования модифицированной системы; d) удаления модифицированной системы из смесительной камеры в пробковом режиме, и причем этот способ отличается тем, что: i. время выдержки в смесительной камере меньше приблизительно 5 мин, и ii. образуются частицы или их агрегаты, причем большинство образовавшихся частиц имеют размер от приблизительно 2 до приблизительно 500 нм.
