Title: Hiroshi Shirakawa: Innovator in Antibacterial Ceramics
Introduction
Hiroshi Shirakawa is a notable inventor based in Kagamihara, Japan. He has made significant contributions to the field of ceramics, particularly in developing antibacterial materials. With a total of 2 patents, his work focuses on enhancing the functionality and application of ceramic products.
Latest Patents
Shirakawa's latest patents include a light-weight antibacterial ceramic and an antibacterial ceramic filter. The light-weight antibacterial ceramic incorporates an antibacterial material produced by loading an antibacterial metal, such as silver, onto a calcium ceramic carrier and an inorganic material like cordierite. This ceramic has a bulk density ranging from 0.6 to 1.2 g/cm³, making it suitable for applications such as roof gardens. The antibacterial ceramic filter, on the other hand, is designed to remove and extirpate various bacteria and suspensions. It contains an antibacterial material produced similarly to the light-weight ceramic, with an aggregate such as mullite and a binder like frit, achieving a porosity of 20% or more. Additionally, he has developed a porous filter for metal hot melt, which comprises ceramic aggregate particles bound by an inorganic binder. This filter significantly improves debris catching ability and initial impregnation of metal hot melt.
Career Highlights
Throughout his career, Shirakawa has worked with prominent companies such as NGK Insulators, Inc. and NGK Adrec Co., Ltd. His experience in these organizations has contributed to his expertise in ceramic materials and their applications.
