Title: Innovations of Tadashi Zenbutsu

Introduction

Tadashi Zenbutsu is a notable inventor based in Bizen, Japan. He has made significant contributions to the field of refractory materials, holding a total of 5 patents. His work focuses on developing innovative compositions that enhance the performance and durability of materials used in high-temperature applications.

Latest Patents

One of his latest patents is a heat-resistant inorganic composition. This invention provides a novel composition useful as a heat-resistant coating material on the surface of metal or ceramic articles or as an adhesive agent for bonding these materials. The adhesive strength of this composition is remarkably strong, preventing peeling even after numerous cycles of rapid heating and cooling. The composition includes a refractory powder of inorganic oxides, such as alumina and silica, along with a powdery inorganic compound with cation-exchangeability and a layered structure, like mica, and an alkali metal silicate or aluminate as a binder. The maximum particle diameter of the powdery inorganic compound is crucial and relates to the average particle diameter of the refractory powder.

Another significant patent is for a carbon-containing refractory composition. This invention is characterized by containing 0.1-10 parts by weight of silicon hexaboride in 100 parts by weight of refractory material, which includes 3-95 parts by weight of carbonaceous material such as graphite and 97-5 parts by weight of refractory aggregate. In this composition, silicon hexaboride oxidizes, producing boron oxide on the surface of the refractory at high temperatures during operation. This process covers the surface of the refractory with a highly viscous molten liquid, protecting the carbonaceous material from oxidation. This innovation provides a refractory with superior oxidation resistance, making it valuable in metallurgy, pig iron production, and steel production.
