Abstract:By some new techniques of reducing impurity and improving physical properties, and by sodium reducing Ta2O5, tantalum powders with high capacitance and other excellent properties were produced, the morphologies were also studied. And by some new techniques of producing niobium or niobium monoxide powders, niobium/niobium monoxide powders with high capacitance were also obtained, which has supplied excellent fundamental material for niobium capacitors.
Key words: high capacitance tantalum powder; high capacitance niobium powder; niobium oxide powder; physical properties
