摘要： The present invention provides a technology for recovering high-content tantalum from tantalum-containing waste with reducing various impurities such as antimony (Sb) and phosphorus (P) which hinder reuse of the tantalum in tantalum capacitors. The method for recovering tantalum from tantalum-containing waste according to the present invention is characterized in that tantalum-containing waste is subjected to an acid treatment and then to an alkali treatment, thereby recovering tantalum. The acid treatment is preferably performed with use of an acid containing hydrochloric acid and the alkali treatment is preferably performed with use of sodium hydroxide or potassium hydroxide. The tantalum-containing waste in the present invention is preferably a tantalum sintered compact collected from a tantalum capacitor.

摘要： A manganese oxide particle having a hexagonal crystal structure or an analogous hexagonal crystal structure with an a-axis length of 8.73±1 Å and a c-axis length of 14.86±1 Å. The manganese oxide particle is preferably produced by a process including mixing an aqueous solution containing manganese (II) and an organic compound having a hydroxyl group while in a heated state with an alkali.
