Title: The Innovations of Shinichi Suenaga

Introduction

Shinichi Suenaga is a notable inventor based in Okayama, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced copper and cuprous oxide powders. With a total of seven patents to his name, Suenaga's work has implications for various applications, including conductive pastes.

Latest Patents

One of Suenaga's latest patents is for a copper powder designed for conductive paste. This innovative copper powder consists of monodisperse and spherical fine copper particles that exhibit a sharp particle size distribution. Importantly, it contains no coarse particles, allowing for the formation of thinner electrode films without negatively impacting electrical characteristics. The method for producing this copper powder involves complexing copper in an aqueous solution while introducing air, followed by the addition of a reducing agent to deposit copper particles through reduction.

Another significant patent is for a cuprous oxide powder that boasts a smaller particle diameter than conventional cuprous oxide powders. The production method involves adding a reducing agent, such as a reducing sugar, to a solution containing copper hydroxide. This process results in the deposition of cuprous oxide particles through reduction. By incorporating ferrous ions into the copper ion solution before forming copper hydroxide, the resulting cuprous oxide powder achieves a mean primary particle diameter of not greater than 0.5 micrometers.
