Title: Innovations of Yoshio Hayashi
Introduction
Yoshio Hayashi is a notable inventor based in Gifu, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced manufacturing methods for ceramic and alumina products. With a total of 2 patents, his work showcases innovative approaches to enhancing material properties and manufacturing processes.
Latest Patents
Yoshio Hayashi's latest patents include a method for manufacturing plate boehmite and a sheet for use in firing base plates. The method for manufacturing plate boehmite involves subjecting an alkaline earth metal compound, selected from calcium, strontium, and barium, along with aluminum hydroxide, to pressurization and heating at temperatures between 150 to 300°C in the presence of water. This process results in a reaction product that is treated with acid to remove residual alkaline earth metal compounds, followed by rinsing with water. The final product is then calcined at temperatures ranging from 450 to 1500°C, resulting in a plate alumina that comprises a mixture of α-alumina and δ-alumina as a major component. The second patent relates to a sheet designed for use in firing ceramic, glass, and metal faced base plates. This sheet consists of a combustible material, such as pulp paper, coated with a layer that includes a high melting point material and carbon powder. This innovative coating effectively prevents shrinkage during firing, ensuring uniformity and preventing adhesion between stacked base plates.
