Abstract
A method of producing a niobium granulated powder, including the steps of: mixing niobium hydride and a metal oxide by a mechanical alloying method to produce a mechanical alloy; pulverizing the mechanical alloy; subjecting the pulverized mechanical alloy to heat treatment to allow the pulverized mechanical alloy to aggregate, to thereby form a granulated product. Also disclosed is a sintered body of the niobium granulated powder, an anode body produced from the sintered body and a capacitor including the sintered body.
