A method of obtaining ceramic membranes containing carbon nanotubes (CNT) is proposed. Gibbsite is thermally activated using the industrial method, and then it is mixed with the CNT–SiO2 composite and lanthanum hydroxide. The resulting mixture is subjected to mechanochemical activation and plasticized with the help of the aqueous solution of nitric acid. The resulting mass is evaporated to the semi–dry state and pressed in the press mold under a pressure of 100 MPa. The pressed tablets of the composition 80 mass % Al2O3 + 17 mass % (CNT–SiO2) + 3 mass % La2O3 are annealed under anaerobic conditions under smooth heating to a temperature of 950 °С. Sintering and transformation of initial oxide phases were studied under usual heating in a muffle furnace and under heating through energy input by means of microwave frequency radiation directly to the initial samples Under the microwave heating of the resulting membranes, a stronger transformation and sample agglomeration are observed than those related to the case of heating in a muffle furnace.
