  • Method of making a valve metal powder for electrolytic condensers and the like
    Patent number: 4582530
    Abstract: In the production of a vanadium group valve metal powder, especially tantalum, the reaction mixture of a double fluoride salt of the valve metal and metallic sodium and/or potassium is doped with sulfur before a melt cake is formed. The melt cake is then leached with water to eliminate central salts leaving the valve metal powder. The sulfur doping provides improved surface area and particle size characteristics.
