Title: Nobuhiro Okuzono: Innovator in Ceramic Filtration Technology
Introduction
Nobuhiro Okuzono is a distinguished inventor based in Ohmuta, Japan. He has made significant contributions to the field of ceramic filtration technology, holding a total of 2 patents. His work focuses on developing advanced materials for filtering molten metals, particularly aluminum.
Latest Patents
Okuzono's latest patents include a ceramic filter and a method for preparing the same. This innovative ceramic filter is designed for filtering molten metals and consists of aggregate particles made from fused alumina and/or sintered alumina, combined with a specific binder material. The binder is present in an amount of 10 to 22 parts by weight per 100 parts of the aggregate particles. The composition of the binder includes 15 to 25% Al₂O₃, 35 to 52% B₂O₃, and a controlled amount of SiO₂ and MgO. The preparation process involves kneading the aggregate particles with the binder, molding, drying, and firing the mixture at temperatures ranging from 1150 to 1300 degrees Celsius.
Another notable patent is a filter specifically designed for the filtration of molten aluminum. This filter is created by binding 100 parts by weight of aggregate particles with 10 to 20 parts by weight of an inorganic binding material. The aggregate particles consist of at least one type of alumina, and the inorganic binding material has a specific raw material composition. The resulting filter exhibits a crystallinity of 10% to 25%, with needle crystals of 9Al₂O₃·2B₂O₃ formed in the binding material.
