Abstract
The possibility of producing high-quality high-capacity tantalum powder from certain types of tantalum wastes by their oxidation and subsequent magnesium thermal reduction is discussed. Capacitor powders with a specific charge of 100000—150000 µC·g–1 and leakage current less than 0.001 μA·μC–1 were obtained.
