  • TITANATE HAVING ALKALI METAL TITANATE BONDED THERETO, PROCESS FOR PRODUCING THE SAME, AND RESIN COMPOSITION CONTAINING TITANATE HAVING ALKALI METAL TITANATE BONDED THERETO
    Publication number: 20100093908
    Abstract: To obtain an alkaline metal titanate adhered to titanate, which is excellent in friction and wear characteristics when used as a friction modifier, and is excellent in mechanical properties and dielectricity when used as a dielectric material, a method for manufacturing the same, and a resin composition containing the same. An alkaline metal titanate adhered to titanate is characterized in that an alkaline earth metal titanate represented by the formula (2) is adhered onto the surface of titanate represented by the formula (1): AxMy?Ti2-(y+z)O4??(1) wherein A and M are different from each other and represent a mono- to trivalent metal, ? represents a defective portion of Ti, X represents a positive real number which satisfies 0<X<1.0, and y and z each represents 0 or a positive real number which satisfies 0<y+z<1.0, and BO·TiO2??(2) wherein B represents one or more kinds of an alkaline earth metals.
