Nickel hollow fiber membranes were prepared by a phase inversion and a sintering method. A nickel hollow fiber support was prepared by spinning the polymer solution containing suspended nickel powders to a hollow fiber precursor which is then sintered at elevated temperature. For these hollow fiber

Ultrathin alumina hollow fibers were prepared by a phase inversion and a sintering method. A polysulfone solution containing well-dispersed alumina powders is spun, which is then sintered at elevated temperature. To increase the packing density of alumina powers in the hollow fiber, 1,4-dioxane was
