Title: Mikio Sakakibara and His Contributions to Alloy Production

Introduction

Mikio Sakakibara is an inventor associated with Chiryu, Japan, and Sumitomo Light Metal Industries, Ltd. His patent work focuses on electrolytic processes and equipment for producing rare-earth metal alloys. He is credited with 2 patents.

Latest Patents

Sakakibara’s listed patents address methods and apparatus for producing alloys containing terbium, gadolinium, dysprosium, and neodymium.

“Process and Apparatus for Producing Alloy Containing Terbium and/or Gadolinium” describes electrolytic reduction in a molten fluoride bath. The process deposits terbium and/or gadolinium onto an iron or cobalt cathode, where the deposited metal alloys with the cathode material. The resulting liquid alloy drips into a receiver beneath the cathode, collects as a molten pool, and is then withdrawn. The bath composition is maintained by replenishing the consumed fluoride compounds.

“Process for Producing Dysprosium-Iron Alloy and Neodymium-Dysprosium-Iron Alloy” concerns electrolytic reduction in a molten fluoride bath using carbon anodes and iron cathodes. Its apparatus includes a refractory electrowinning cell, a receiver for collecting the liquid alloy, siphoning equipment for removing the molten product, and a feeding mechanism that advances the iron cathode into the bath while maintaining a predetermined current density.

Career Highlights

The patents highlight Sakakibara’s work on producing rare-earth alloys through molten-salt electrolysis. Their processes combine controlled bath compositions, electrodeposition, alloy formation at the cathode, and collection of the molten product. These techniques are directed toward producing terbium-, gadolinium-, dysprosium-, and neodymium-containing alloys.
