Title: Yasuhiro Kamahori: Innovator in Nickel-Rhenium Alloy Technology
Introduction
Yasuhiro Kamahori is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of materials science, particularly in the development of nickel-rhenium alloy powders. With a total of 3 patents to his name, Kamahori's work has implications for the electronics industry, especially in multilayer ceramic electronic components.
Latest Patents
Kamahori's latest patents focus on the formulation of nickel-rhenium alloy powders and the conductor pastes derived from them. One of his inventions provides a nickel-rhenium alloy powder that contains nickel as a main component, 0.1 to 10% by weight of rhenium, and 50 to 10,000 ppm of silicon. This alloy powder is particularly suitable for forming internal electrode layers in multilayer ceramic electronic components. The innovation allows for delayed sintering initiation and slows down the progress of sintering during firing, which is crucial for maintaining the integrity of extremely fine powders.
Another patent describes a nickel-rhenium alloy powder with an average particle size of 0.05 to 1.0 µm. This powder features a surface oxide film containing nickel oxide and rhenium oxide, with an oxygen content of 0.1 to 3.0% by weight. This specific formulation enhances the sintering shrinkage behavior of electrode layers and ceramic layers, preventing issues such as electrode spheroidizing caused by oversintering. As a result, thinner and denser internal electrodes with excellent continuity can be achieved.
