Title: Makoto Kameda and Silica Composite Oxide Particles
Introduction
Makoto Kameda is an inventor associated with Yamaguchi, Japan, and Tokuyama Corporation. His patent work includes a method for producing silica composite oxide particles with a high content of non-silica metal oxide and a controlled particle-size distribution.
Latest Patents
Kameda is credited with 1 patent: “Silica Composite Oxide Particles and Method of Producing the Same.” The invention concerns particles comprising silica and a metal oxide other than silica, with the non-silica metal oxide making up 30 to 50 mol% of the composition. It also specifies a coefficient of variation in particle diameter of no more than 30%.
The patent describes particles with at least 30 mol% non-silica metal oxide, a composition that the patent states had not previously been achievable through existing production methods. The particles are characterized by their spherical shape and monodispersion properties.
Career Highlights
Kameda’s listed patent reflects work on the composition and production of advanced oxide particles. The invention’s focus is on combining a substantial proportion of non-silica metal oxide with consistent particle size and shape.
Collaborations
Kameda’s listed coworkers include Hiroshi Kato and Michimasa Tamura. His company affiliation is Tokuyama Corporation.
Conclusion
Makoto Kameda’s patent highlights a particle-production approach designed to achieve high non-silica metal oxide content alongside spherical shape and uniform particle size.
