  • Method of manufacturing alkali metal titanate and hollow body particle thereof, product thereof, and friction material containing the product
    Patent number: 8398952
    Abstract: The present invention is to provide a method of manufacturing a potassium titanate adapted for a friction material of a friction slide member. The present invention includes the steps of uniformly mixing an aggregate or a granulation of a titanium compound and a potassium compound with a vibration rod mill to form a mixture and sintering the mixture for reaction one another in order to manufacture a desired potassium titanate with ease and low cost.
    Type: Grant
    Filed: March 27, 2008
    Date of Patent: March 19, 2013
    Assignee: Toho Titanium Co., Ltd.
    Inventors: Koji Tanimizu, Naomichi Hori, Nobuo Kamishima
  • Method of manufacturing alkali metal titanate
    Patent number: 8178072
    Abstract: The present invention provides a method of manufacturing an alkali metal titanate, the method including at least a first step of mixing a titanium compound and an alkali metal compound to prepare a first mixture and sintering the first mixture, and a second step of adding the alkali metal compound to the sintered body, which is formed at the first step, to prepare a second mixture and sintering the second mixture. The present invention provides the alkali metal titanate having a desired composition and a single-phase.
