Title: Takashi Higashiogawa: Innovator in Spherical Silica Particle Manufacturing
Introduction
Takashi Higashiogawa is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of materials science, particularly in the manufacturing of spherical silica particles. His innovative methods have implications for various applications, including the electronics industry.
Latest Patents
Higashiogawa holds a patent for a method of manufacturing spherical silica particles. This method involves processing a coagulant derived from an aqueous alkali metal silicate solution in an acid-containing solution, followed by washing with water. The process includes wet-grinding the amorphous silica obtained in a liquid dispersion medium to create a fine particle silica suspension with a weight average particle size of 10 µm or less. The suspension is then spray-dried with hot air and sintered to produce high-purity spherical silica particles. This invention allows for the production of silica particles with high solidity and adjusted surface smoothness, making them suitable for use as sealant fillers in highly-integrated IC electronic parts.
