Title: Hiroshi Takashima: Innovator in Molybdenum and Titanium Production
Introduction
Hiroshi Takashima is a notable inventor based in Yasugi, Japan. He has made significant contributions to the fields of materials science and engineering, particularly in the production of molybdenum and titanium. With a total of 5 patents to his name, Takashima's work has advanced the efficiency and quality of metal production processes.
Latest Patents
One of Takashima's latest patents is a method for producing a molybdenum target. This innovative method allows for the efficient production of a low-oxygen and high-density molybdenum target by utilizing the unique characteristics of different molybdenum starting material powders. The process involves mixing a specific molybdenum powder A, which is created by reducing molybdenum oxide and crushing it to an average particle diameter of 2-15 micrometers, with a molybdenum powder B, derived from crushing a bulk starting material with a density of at least 6.64 x 10 kg/m. This mixed powder is then sintered under pressure to achieve the desired target.
Another significant patent by Takashima is a method for producing titanium metal. This process involves generating an RF thermal plasma discharge using a plasma torch equipped with an RF coil. The method reduces titanium tetrachloride to titanium metal by introducing titanium tetrachloride and magnesium into the RF thermal plasma discharge. The titanium metal is then collected or deposited at a temperature that is not lower than the boiling point of magnesium chloride and not higher than the boiling point of titanium metal.
