Title: Ken-ichi Mizuno: Innovator in Alumina-based Sintered Materials
Introduction
Ken-ichi Mizuno is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of materials science, particularly in the development of alumina-based sintered materials. With a total of 3 patents to his name, Mizuno's work showcases his expertise and innovative spirit.
Latest Patents
Mizuno's latest patents include a homogeneous alumina-based sintered material that exhibits excellent grindability, low porosity, and high flexural strength. This material is free of color unevenness and fluctuations in density. The process involves measuring predetermined amounts of Al₂O₃ powder, MgO powder, CaCO₃ powder, and SiO₂ powder, which are then mixed in a ball mill. The mixture is granulated using a spray dryer and hydrostatically pressed to obtain a molded product. This product is sintered at temperatures ranging from 1,550°C to 1,650°C, particularly between 1,600°C and 1,650°C, under atmospheric pressure for two hours. The resulting alumina-based sintered material has a 50 percent cumulative grain size distribution in diameter ranging from 4 to 15 µm, with a porosity of not more than 5%. This innovative material demonstrates a maximum load current during grinding of not more than 1.0 A/mm and a four-point flexural strength of not less than 300 MPa.
