PCT No. PCT/NL94/00069 Sec. 371 Date Nov. 29, 1995 Sec. 102(e) Date Nov. 29, 1995 PCT Filed Mar. 30, 1994 PCT Pub. No. WO94/23829 PCT Pub. Date Oct. 27, 1994In order to produce ceramic hollow fibers, in particular hollow fiber membranes for microfiltration, ultrafiltration and gas separation, a paste is made filling a polymer binder system with a ceramic powder. The paste is processed by extruding through a spinneret to give hollow fibers. The binder system is removed with the aid of thermal diffusion and the powder particles are sintered to each other.
