Abstract
A porous diaphragm for an electrolytic cell for the electrolysis of alkali metal halides is comprised of a thermoplastic support fabric impregnated with particles of a siliceous composition. The thermoplastic support fabric has an anode side, a cathode side opposite the anode side, and a thickness of at least 0.3 millimeters. The cathode side has a greater hydrophobicity than the anode side. To provide greater hydrophobicity which results in controlled, reduced cell voltages, for example, the cathode side of the support fabric is treated with an oxidizing agent.
