Abstract. A process based on oxidation treatment at elevated temperature, followed by mechanical separation and chemical treatment, was investigated to develop an effective process for recycling tantalum from capacitor scraps. By this process, tantalum oxide powder, free of SiO 2 or other impurities, was recovered from capacitor scrap.

The experimental results obtained by treating Ta–Si–O alloys of known silicon and oxygen contents at temperatures ranging from 2073 to 2273 K under 1310 23 Pa pressure for 2 h indicated the occurrence of silicon deoxidation. In this temperature range, oxygen removal has occurred faster and to a lower residual level in Ta–O alloys ...
