Fe₂O₃-doped SnO₂ ceramic membranes were fabricated by an innovative approach based on interface segregation. The membranes exhibited outstanding mechanical resistance, which was attributed to doping-induced increase in the grain boundary interface area and decrease in the crystallite size. The membranes were sintered at different temperatures from 500 °C to 1000 °C. Most pore diameters were in the range of 0.01-0.1 µm, and the pore diameters of both doped and undoped membranes could be well controlled by adjusting the sintering temperature without any sacrificial material. The permeability results showed that the membranes could be used for nano-, ultra-, and microfiltration applications. The mechanical resistance of Fe₂O₃-doped SnO₂ membranes was around three times higher than that of pristine SnO₂ membranes. The compressive strength of the doped SnO₂ membranes sintered at 1000 °C was 26.8 MPa, while that of the undoped membranes was 10.1 MPa.

通过基于界面隔离的创新方法，制备了掺杂Fe ₂ O _3的SnO ₂陶瓷膜。该膜表现出优异的机械阻力，这归因于掺杂引起的晶界界面面积的增加和晶粒尺寸的减小。将膜在500°C至1000°C的不同温度下烧结。大多数孔径在0.01-0.1μm的范围内，并且可以通过调节烧结温度而无需任何牺牲材料来很好地控制掺杂膜和非掺杂膜的孔径。渗透性结果表明，该膜可用于纳滤，超滤和微滤应用。Fe ₂ O的机械电阻₃掺杂SnO ₂膜比原始SnO ₂膜高约三倍。在1000℃下烧结的掺杂SnO ₂膜的抗压强度为26.8MPa，而未掺杂膜的抗压强度为10.1MPa。
