Abstract

See full text

The invention relates to a synthetic diaphragm for chlor-alkali cells with improved energy consumption and gas separation characteristics. The diaphragm comprises a network of polymer fibers bound to a hydrophilic ceramic material containing zirconium chemically bound to hydroxyl groups. The ceramic material is obtained starting from ZrO2 by a process of hydration under vacuum which can be carried out directly in the cell by means of suitable equipment.
