Fabrication of metal–ceramic membranes withstanding extreme operating conditions

详细

Preparation of bilayer metal–ceramic membranes with porous stainless steel supports and selective layers based on TiO₂ has been described. The resulting membranes have high air and distilled water fluxes. Pressure-hold tests have shown that the experimental samples of stainless steel supports withstand pressure drop up to 1.9 MPa. Toxicological tests showed the possibility of using these membranes in medical industry. These membranes can be used for microfiltration in hot corrosive environments as high-efficiency filters in chemical and microbiological industries and fine filters in food production processes, membrane sterilization, and other fields.
