Title: The Innovative Mind of Yasuo Araki
Introduction
Yasuo Araki, an accomplished inventor located in Sakai, Japan, has made significant contributions to the field of materials science through his innovative patents. With a total of two patents to his name, Araki continues to push the boundaries of technology in his domain.
Latest Patents
Araki's latest patents showcase his expertise and creativity. The first patent involves "Nickel hydroxide particles and production and use thereof". This invention provides nickel hydroxide secondary particles composed of agglomerates of primary particles that are distinctly shaped like a triangular prism or triangular plate. Each outer face of these particles resembles a substantially equilateral triangle, with a side length ranging from 1 to 10 micrometers. The patent also discusses the creation of lithium nickel composite oxide secondary particles by mixing nickel hydroxide secondary particles with a lithium compound and sintering the mixture at temperatures between 600°C and 1000°C in an oxidative atmosphere.
The second patent details a "Method of producing cobalt-modified magnetic particles". This method entails heating an aqueous suspension of ferric hydroxide at a temperature range of 100°C to 250°C under alkaline pH conditions. It involves the use of a water-soluble organic or inorganic compound that acts as a growth regulating agent, as well as the inclusion of α-ferric oxide seed crystals. The innovative approach converts α-ferric oxide into γ-ferric oxide through reduction and subsequent oxidation while optimizing conditions to modify γ-ferric oxide particles using ferrous hydroxide and cobaltous hydroxide.
