Title: Hiroshi Kimura: A Pioneer in Magnetic Powder Innovations
Introduction
Hiroshi Kimura is a notable inventor from Okayama, Japan, recognized for his significant contributions to the field of magnetic powder technology. With two patents to his name, he has made impactful advancements that promise to enhance various applications in electronics and materials science.
Latest Patents
Hiroshi Kimura's latest innovations include two key patents focused on the development of advanced magnetic powders. The first patent outlines a method for producing a magnetic powder chiefly composed of iron nitride (FeN). This process involves starting with an oxy-hydroxide or oxide of iron, which is then reduced to iron powder using hydrogen gas. Following this, the iron powder is nitrided into FeN particles at temperatures not exceeding 200°C, ensuring the atomic percent ratio of noble metal to iron ranges from 0.01 to 10%. This innovation not only aims to improve noise characteristics in media applications but also enhances storage stability.
His second patent presents an iron nitride system magnetic powder characterized by particles primarily comprised of Fe16N, with an average diameter of up to 25 nanometers. This powder includes adhesion of elements like silicon, phosphorus, and titanium. The C/Fe atomic ratio is optimized between 0.5 to 30%, and the (Si+P+Ti)/Fe atomic ratio is maintained between 0.1 to 10%. The patented powder displays remarkable ignition temperatures, tap densities, and stability under defined environmental conditions, making it suitable for various high-performance applications.
