Outline of Final Research Achievements

A metallic titanium and zirconium alloy particles for electrolytic capacitor applications was produced by electroless reduction with a calcium reductant in calcium chloride molten salt. The reduction rate of oxide was observed to increase with decreasing particle size; accordingly, the residual oxygen content in the reduced titanium decreases. A micro-porous Ti-Zr alloy with low oxygen content and large surface area was successfully fabricated by electroless reduction under optimal conditions.
