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.
