Abstract

Керамический зернистый материал включает частицы глинозема, имеющие удельную площадь поверхности (УПП), не менее, чем 15 м/г и не более, чем 75 м/г, и сферичность, соответствующую, по меньшей мере, одному из двух показателей: (1) средняя округлость, не менее, чем 0,710 за данными корреляционного анализа изображения на округлость, и (2) вогнутость менее, чем 20 %, которая определяется как процент частиц оксида алюминия в выборке из, по меньшей мере, 100 частиц, имеющих вогнутую внешнюю периферическую поверхность, которая простирается на расстоянии, не менее, чем 10 % d, при исследовании с помощью трансмиссионной электронной микроскопии (ТЭМ), причем такой вогнутый участок внешней поверхности имеет отрицательный радиус кривизны, если смотреть изнутри частицы.
