Abstract

An improved diaphragm for an electrolytic cell is prepared by mixing a slurry of asbestos fibers with a dispersion of titanium dioxide in isopropyl alcohol, depositing the treated asbestos fibers onto a cathode, heating the diaphragm to an elevated temperature of from about 100.degree. C. to about 300.degree. C., and allowing the diaphragm to cool. The diaphragm prepared according to this process exhibits improved mechanical strength and integrity as well as a decrease in electrical energy consumption in comparison to diaphragms prepared using conventional techniques.
