description FIELD: ceramics. SUBSTANCE: invention relates to treatment of ceramic granulated materials, in particular to surface strengthening and hydrophobization of granules, which may be employed in oil and gas production industry. Strengthening and hydrophobization of granules are accomplished by coating granule surfaces with liquid organosilicon compounds, which are sprayed to form fluidized state at 250-800(r), after which granules are cooled at cooling rate 50 to 200(r)/h. Organosilicon compounds are selected from solution or emulsion of organosilicon liquid or liquid glass aqueous solution, which can further contain 0.01 to 1% of sodium tetrafluoride. EFFECT: enabled relatively rapid and inexpensive formation of coating without their conglutination. 5 cl, 2 dwg
