Abstract

Карботермический процесс получения массы, содержащей карбид алюминия, путем вдувания углерода и глинозема в расплавленный алюминий, перегретый выше 1400°С. Углерод реагирует с расплавленным алюминием с образованием массы карбида алюминия и глинозема. Массу можно нагревать в диапазоне от 1700 до 2000°С с получением металлического алюминия и монооксида углерода.
