Abstract

A process for preparation of low-alkali special alumina comprises activation of aluminum hydroxide by the heating. The activation is carried out with the rate of 200-250°C/sec during 2-3 sec. The invention relates to non-ferrous metallurgy and is used for obtaining of alumina ceramics, manufacturing of integral microschemes, alumina substrates etc.
