METHOD OF PREPARING ELECTROLYTIC MANGANESE DIOXIDE |
摘要 |
<p>A method for the preparation of electrolytic manganese dioxide is provided employing improved cathodes, said cathodes being characterized by their reduced tendency to corrode and undergo buildup of current inhibiting scale under electrolytic conditions. The improved cathodes are fabricated from copper comprised of at least about 99.95 weight percent of copper, from about 0.001 to about 0.085 weight percent of silver and up to about 0.003 weight percent of phosphorous. The weight ratio of phosphorous to silver in said copper cathode will be no greater than about 2.0 to 1.0.</p> |
