  • Electrode and electrolytic cell containing same
    Patent number: 6309523
    Abstract: An electrode is disclosed having a coating on part of the electrode, e.g., a front face, comprising the oxides of tin, antimony, at least one platinum group metal and at least one valve metal. Another part of the electrode, such as a back face, has a coating comprising the oxides of at least one valve metal and at least one platinum group metal. The electrode can be generally plate-shaped and most desirably has at least one chamfered corner. The electrode is particularly useful in a cell wherein brine electrolyte is electrolyzed to prepare a disinfectant solution containing hypochlorite. The disinfectant solution can be especially serviceable, such as in maritime application, for treating water, e.g., freshwater as represented by desalinated water.
    Type: Grant
