ABSTRACT:
A diaphragm for use in the electrolysis of alkali metal chloride brines in electrolytic diaphragm cells is comprised of a support fabric impregnated with a non-fibrilic active component containing silica. The support fabric has a non-continuous coating of an electroconductive metal on one side of the fabric. Suitable electroconductive metals include nickel, nickel alloys, gold, gold alloys, platinum group metals, platinum group metal alloys, and mixtures thereof.
The diaphragms are physically and chemically stable, provide reduced cell voltages during operation of the cell and have increased operational life.
