Title: Masataka Himeno: Innovator in Aluminum Nitride and Dental Materials
Introduction
Masataka Himeno is a notable inventor based in Tokuyama, Japan. He has made significant contributions to the fields of materials science and dental technology. With a total of 5 patents to his name, his work focuses on innovative materials that enhance performance and usability.
Latest Patents
One of his latest patents is for an aluminum nitride powder containing no coarse particles. This aluminum nitride powder is characterized by a very small amount of coarse particles, which provides a resin composition with high affinity for resins and excellent moisture resistance. The powder has a volume average particle diameter D50 ranging from 0.5 to 7.0 µm, a D90/D50 ratio of 1.3 to 3.5, and a BET specific surface area of 0.4 to 6.0 m/g. The classification process removes coarse particles whose diameter exceeds five times D90, resulting in a surface-modified aluminum nitride powder that exhibits high filling properties in resin and outstanding moisture resistance and insulating properties.
Another significant patent is for a photo-curable reparative material for dental use. This dental restorative comprises 100 parts by weight of a polymerizable monomer, 0.01 to 5 parts by weight of a photopolymerization initiator of acylphosphine oxide, and 200 to 1900 parts by weight of a mixed inorganic filler. The restorative features excellent handling properties and allows for the production of a cured product with high fracture toughness and a glossy surface.
