Abstract: The technology of preparing capacitor tantalum powder with carbon reducing-high temperature sintering has been investigated. Two-stage direct reduction is described, and its technical conditions and product quality are listed in this paper. The advantages of the tecdnology, compared with other processes, are good product systematization, wide specific electric capacity (500—8000μF. V/g), wide-range working voltage for dry electrolyte capacitor(6.3—125V), high metallic recovery of 93.38%, and excellent inviolated conditions.
