Abstract
A three-dimensional network of rigid, porous hollow filament of inorganic material is provided which has high flux capability in treating fluid for separation purposes. The network is made by coating a continuous combustible core with a paste of the inorganic material, fabricating the resultant coated core into the network, followed by firing the coated core to burn off the core and sinter the coating to rigid porous hollow filament.
