Title: Kiyoshi Ozawa: Innovator in Antimonic Acid Technology
Introduction
Kiyoshi Ozawa is a notable inventor based in Ibaraki, Japan, recognized for his contributions to the field of materials science. He holds a total of four patents, showcasing his innovative approach to developing advanced materials with practical applications.
Latest Patents
One of his latest patents is for a high-proton-conductive antimonic acid film. This invention aims to provide an antimonic acid film that exhibits excellent conductivity and a high response to humidity. It is particularly useful as a high-performance humidity sensor, hydrogen gas sensor, or in hydrogen fuel cells. The film comprises single crystals of cubic antimonic acid dispersed in amorphous antimonic acid, created by reacting metallic antimony or an oxygen-containing compound with hydrogen peroxide. The resultant reaction solution serves as the raw material for forming the film on an insulated substrate.
Another significant patent by Ozawa details a method for producing single crystals. In this method, a seed crystal is connected with a polycrystal at one end. The connected crystal material is then melted in a zero-gravity or microgravity environment without any container, allowing for the growth of a single crystal.
