Abstract

Способ получения полых керамических или металлических микросфер, включающий стадии получения керамической или металлической суспензии, содержащей керамические или металлические порошки, воду и диспергатор и имеющей определенное содержание твердой фазы, в суспензию со стабильной пеной путем использования вспенивающего агента; подачи стабильной вспененной суспензии в устройство центробежного распыления для распыления на полые капли суспензии, при этом распыляя в формовочную камеру, быстро высушивая для получения сырца полых микросфер; сбора сырца полых микросфер и спекания. Полученная полая микросфера имеет размер частицы 0,001-1,5 мм и высокое качество и низкую стоимость. Способ является приспособленным для превращения различных неорганических порошковых материалов в полые микросферы. В настоящем изобретении также предложено устройство для получения полых керамических или металлических микросфер и полые микросферы.
