ABSTRACT:
A valve metal powder by is prepared by a particular set of sequential steps that involves the use of precursor having preformed morphology. The method by which the valve metal is prepared includes a stabilization step that results in the valve metal powder having secondary and tertiary structures that each corresponds to the secondary and tertiary structures of the precursor. Also described is a method of producing solid electrolyte capacitors that include the valve metal powder of the present invention.
