  • Modified calcium aluminate compound and production method therefor
    Patent number: 11299398
    Abstract: The present invention provides a novel method for producing a calcium aluminate compound having a modified surface. The present invention provides: a method for producing a modified calcium aluminate compound characterized by irradiating a calcium aluminate compound dispersed in an organic dispersion medium with a femtosecond laser, thereby modifying the surface of the calcium aluminate compound; and a modified calcium aluminate compound characterized by being obtained by this method and having at least one of an OH group, a CO group, a CH group, and an NH group.
    Type: Grant
    Filed: February 13, 2017
    Date of Patent: April 12, 2022
    Assignee: NEW-TECH INC.
    Inventors: Kazuyuki Hirao, Heidy Visbal, Minami Hirano, Susumu Hikazudani, Satoshi Yoshida, Emi Shono
  • MODIFIED CALCIUM ALUMINATE COMPOUND AND PRODUCTION METHOD THEREFOR
    Publication number: 20210188653
    Abstract: Prior art documents do not describe a method for modifying the surface of a calcium aluminate compound, much less describe a method for controlling the particle diameter of a calcium aluminate compound. The present invention provides a novel method for producing a calcium aluminate compound having a modified surface. The present invention provides: a method for producing a modified calcium aluminate compound characterized by irradiating a calcium aluminate compound dispersed in an organic dispersion medium with a femtosecond laser, thereby modifying the surface of the calcium aluminate compound; and a modified calcium aluminate compound characterized by being obtained by this method and having at least one of an OH group, a CO group, a CH group, and an NH group.
