Title: Tomohisa Tonogaki: Inventor in Perovskite Complex Oxide Powder Preparation.

Introduction

Tomohisa Tonogaki is an inventor associated with Shiga, Japan, and Murata Manufacturing Co., Ltd. His work includes a method for preparing high-crystallinity barium titanate powder, a perovskite complex oxide.

Latest Patents

Tonogaki is associated with 1 patent. The patent describes preparing a perovskite complex oxide powder with the formula ABO₃, specifically barium titanate (BaTiO₃). In the method, barium hydroxide is fused by heating and then reacted with titanium oxide powder having a specific surface area of at least 250 m²/g. This produces cubic crystalline BaTiO₃, which is calcined to yield fine tetragonal crystalline powder with high crystallinity. The process aims to produce high-quality BaTiO₃ at low cost.

Career Highlights

Tonogaki’s patent work focuses on improving the preparation of crystalline ceramic materials. The disclosed method combines controlled reaction and calcination steps to obtain fine, highly crystalline BaTiO₃ powder.

Collaborations

Tonogaki’s listed coworkers include Atsuhiro Torii and Masaru Kojima. His company affiliation is Murata Manufacturing Co., Ltd.

Conclusion

Tomohisa Tonogaki’s patent describes a cost-conscious method for producing fine, high-crystallinity BaTiO₃ powder, reflecting his contribution to materials innovation.
