Title: Innovations of Yoshiharu Konya
Introduction
Yoshiharu Konya is a prominent inventor based in Annaka, Japan. He has made significant contributions to the field of materials science, particularly in the development of silica-containing compounds. With a total of 12 patents to his name, Konya's work has had a substantial impact on various industrial applications.
Latest Patents
One of his latest patents is for the production of spherical particles of silica-containing compound oxide. This innovative method utilizes a halogen-free siloxane and an organometallic compound, allowing for the creation of spherical particles that are substantially halogen-free. These particles consist of 0.5-99% by weight of metal oxides and the balance of silica, with a particle size ranging from 10 nm to 3 µm. They are particularly useful as fillers in epoxy resin-based semiconductor sealants and as refractive index modifiers.
Another notable patent involves the preparation of hydrophobic silica fine powder. This process includes premixing hydrophilic silica fine powder with a hydrophobizing agent, followed by mixing in a ball mill and heating in an ammonia or amine-containing atmosphere. The resulting powder has an aerated bulk density of 100-300 g/l, a specific surface area of 40-300 m/g, and a primary particle diameter of 10-120 nm. This hydrophobic silica is less bulky, easy to handle, and stable in mixtures.
