ABSTRACT:
Disclosed is a method of preparing a fibrous, alkali metal chloride brine permeable asbestos diaphragm. The diaphragm is prepared by placing a first electrode in a liquid composition containing asbestos fibers and a surfactant. The liquid composition is maintained basic during the process and an electrical potential is maintained between the electrode on which the asbestos is to be deposited and a second electrode.
