Abstract The inorganic ceramic membrane supports with Luochuan loess as aggregate, SDBS as sintering aid were prepared by extrusion-molding and solid particle sintering method. The effect of the holding time on the properties of ceramic membrane supports was mainly studied. The crystal phase, microscopic morphology, porosity, flexural strength, acid-base corrosion rate and pure water permeability of ceramic supports were characterized by testing methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), mercury intrusion method, three-point bending method, mass loss method, self-made pure water flux measurement device. The results show that with the holding time increasing, the pure water flux of the support increases first and then decreases, the bending strength continues to increase, the corrosion resistance increases gradually, the liquid phase increases gradually, and the grains tend to mature and complete. The pure water flux, flextural strength, average pore throat radius, acid and alkali corrosion rate of the support sintered at 1 050 ℃ for 20 h are 2 570.47 L/(m²∙h∙MPa), 38.91 MPa, 2.39 μm, 0.18% and 0.17% respectively, indicating that the support can be used as an inorganic ceramic membrane carrier for use in the field of water treatment.

Key words： inorganic ceramic membrane supports loess holding time pure water permeability flexural strength
