Title: Hiroshi Miyake: Innovator in Chromium Production

Introduction

Hiroshi Miyake is a notable inventor based in Yamagata, Japan. He has made significant contributions to the field of materials science, particularly in the production of chromium and its alloys. With a total of 2 patents, his work has implications for various industrial applications.

Latest Patents

Miyake's latest patents include a chromium additive and a method for producing metallic chromium. The chromium additive is defined by the formula: Cr.sub.x C.sub.y O.sub.z, where 0.04 ≤ y ≤ 0.35, and 0.03 ≤ z ≤ 0.30 for x=1. This additive exhibits an X-ray diffraction peak at d=3.32 Å (2θ=26.8°). The process for producing metallic chromium involves several steps, starting with carbon reduction of chromium- and iron-containing ore to obtain ferro-chrome. This is followed by treatment with a chlorinating agent to produce an aqueous solution containing chromium chloride and ferrous chloride. The ferrous ion is then oxidized into a ferric ion, which is extracted from the solution. Finally, the aqueous chromium chloride solution is treated in an oxidizing atmosphere to convert it to chromic oxide, which is reduced into metallic chromium.
