Article is devoted to the study of sodium silicate solute mass transfer mechanism in capillary under microwave radiation action. To achieve this goal, original technique, which allows structure of sodium silicate solute at different stages of it’s drying in the field of microwave radiation photographing, has been used. Based on research results description of sodium silicate solute mass transfer mechanism in flat capillary upon heating by microwave radiation has been first developed. According to the data obtained, transfer of sodium silicate solute in capillary proceeds in stages according to scheme similar to chain reaction. Sequence of these stages is as follows: self-encapsulation of sodium silicate solute water solution; vapor bubble appearance in capsule; vapor pressure in capsule increasing; destruction of capsule shell and ejection of sodium silicate solute that has not hardened inside the capsule; complete removal of sodium silicate solute from capsule and its destruction under the influence of high vapor pressure; finalization of the vapor movement ejected outside the capsule of sodium silicate solute; its repeated self-encapsulation, etc. This process repeats until water is completely removed from the treated sodium silicate solute. Stages and certain cyclical nature of foam structure formation in sodium silicate solute under microwave radiation influence is the reason for its uneven pores dispersion and its gas permeability. Sodium silicate solute with silicate module from 2.8 to 3.0 processing by microwave radiation can reduce water content in dried sodium silicate solute to a relative mass content of less than 0.02%.
