Abstract
The paper describes the theory and practice of low-temperature decomposition of alumina solutions. Scientific substantiation of the use of activated nepheline solution as an inoculum for HASN crystallization is given. Materials of experimental study of chemical equilibrium and kinetics of the decomposition process in the system activated nepheline alcohol - aluminate solution are presented. The possibility of achieving technological low-temperature factors of the process sufficient for the subsequent complete deposition of silica is shown.
