Title: The Innovations of Tamotsu Mizuno
Introduction
Tamotsu Mizuno is a notable inventor based in Ube, Japan. He has made significant contributions to the field of chemistry, particularly in the preparation and refinement of various chemical compounds. With a total of 3 patents to his name, Mizuno's work has had a considerable impact on the industry.
Latest Patents
Mizuno's latest patents include a process for preparing calcium hydrogen phosphate anhydride suitable as a raw material for phosphate phosphors. This process involves precipitating CaHPO.sub.4.2H.sub.2 O by mixing aqueous solutions of NaNH.sub.4 HPO.sub.4.4H.sub.2 O and CaCl.sub.2.6H.sub.2 O at temperatures ranging from 5 to 40 degrees Celsius. The entire quantity of CaHPO.sub.4.2H.sub.2 O is converted to CaHPO.sub.4 in one batch by introducing it into acidified water maintained above 80 degrees Celsius. The resulting crystalline CaHPO.sub.4 exhibits different crystal habits depending on the pH of the hot water used.
Another significant patent involves the process of refining sodium hexafluorosilicate containing gypsum. This method allows for the economical refinement of crude sodium hexafluorosilicate while minimizing the loss of fluorine. The process begins with making the crude fluorosilicate react with an alkali metal compound to form a soluble sulfate. The solid component is then treated with an acid solution in the presence of sodium ions, preferably at elevated temperatures, to crystallize sodium hexafluorosilicate.
