Mass transfer between the liquid and solid phases of the reaction mix during the metakaolin crystallization into the powdered Zeolite LTA has been studied. The metakaolin crystallization has been shown to occur through the formation stage of the amorphous sodium aluminosilicate close by its composition to the Zeolite LTA (Linde type A). It has been established that during thermochemical processing of the metakaolin in aqueous sodium hydroxide solution the solid-liquid mass transfer occurred already at 30oC on account of the interaction of the metakaolin with polyhydroxy complexes of sodium. The stage rate grows as the temperature is elevated, and the sodium hydroxide concentration in the liquid phase of the reaction mix increased. All the above mentioned witnesses the crystallization centers to arise at the boundary of the solid and liquid phases of the reaction mix.
