Title: **Yoshio Kawasumi: Innovator in Composite Powder Technology**
Introduction
Yoshio Kawasumi, an accomplished inventor based in Urawa, Japan, has made significant contributions to the field of composite materials. With a total of six patents to his name, his work primarily focuses on the production and enhancement of composite powders coated with noble metals. His inventive processes have the potential to revolutionize various industrial applications.
Latest Patents
One of Kawasumi's most notable recent patents is the "Process of Producing Composite Powder Coated with Noble Metal." This innovative method involves adding a powder of a metal or alloy that is less noble than the noble metal to a metallic sulfide, carbon, activated charcoal, metallic carbide, or metallic oxide powder. After thoroughly mixing, a noble metal solution is introduced, resulting in a cementation reaction that coats the composite powder with the noble metal.
Another key patent is titled "Process of Producing Multilayer-Coated Composite Powder." This process entails treating a core powder with first metallic ions and a reducing metallic powder to create a single-layer coated powder. By subsequently treating this coated powder with second metallic ions, either alone or in conjunction with a reducing metallic powder, Kawasumi enables the formation of multilayer coatings. This innovative approach can be repeated as necessary to achieve the desired number of coating layers.
Career Highlights
Kawasumi has held pivotal roles at notable companies, including Nihon Kogyo Kabushiki Kaisha, where he significantly contributed to research and development efforts. His expertise in the field of composite materials has allowed him to forge a path in advancing the applications of coated powders.
