ABSTRACT:
A novel process for preparing a diaphragm-deposited activated cathode for use in a chlor-alkali cell is disclosed. The process involves heat-treating the activated cathode in an inert atmosphere, such as a nitrogen atmosphere, or a reducing atmosphere, such as a hydrogen atmosphere, during the baking or sintering of the diaphragm.
Diaphragm-deposited activated cathodes prepared according to this invention exhibit better adhesive and stability than those which are prepared using conventional techniques. This, in turn, permits sustained operation in a chlor-alkali cell at a lower voltage for substantial energy savings.
