Abstract
The mechanism of mass crystallization of synthetic gibbsite at decomposition of aluminate solutions is proposed. The leading role of nucleation and supersaturation in the formation of granulometry of aluminum hydroxide precipitate is shown. The methodology and experimental results of induction period determination during gibbsite precipitation from aluminate solution are presented. The surface energy of solid phase formation during carbonization of aluminate solution as a function of critical nucleation size is determined.
