Abstract

A mesopore sized YSZ-SiO₂ ceramic hollow fibre membrane has been fabricated using a novel phase transition technique. The N₂ or H₂ single-gas permeation under relatively high pressure gradients reveals that the YSZ-SiO₂ membrane is gas permeable, and the mean pore diameter of the membrane is less than four nanometers. Examination of the microstructure of the membrane shows that the YSZ-SiO₂ ceramic is well sintered and is free of packing-pores. By analyzing the phase transition of the SiO₂ and the microstructure of the membrane, it is believed that the pores in the membrane for the gas permeation were created by the β → α transition of cristobalite.
