FIELD: building, and petroleum-extracting industries. SUBSTANCE: finely dispersed silicate is hydrothermally treated and is simultaneously ground by hydroacoustic method. Water and reaction mixture are circulated using magnetic field with intensity of 4000-10000 E. EFFECT: shorter time for dissolution of alkali metal silicate, smaller amount of insoluble deposit in reaction mixture and reduced caking of dissolved silicate lump on reactor bottom. 1 ex, 1 dwg, 1 tbl
