  • Electrically conductive fibers of Ti4O7 and Ti5O9
    Patent number: 7232558
    Abstract: Solid, shaped and fired fibers of Ti4O7 and Ti5O9 are made by firing TiO2 fibers in a reducing atmosphere. In a first aspect, the TiO2 fibers are made by extruding into air a viscous TiO2 gel and heat treating the resulting green fibers to remove solvent, decompose and to volatilize undesired constituents to form electrically conductive, refractory fibers of Ti4O7 and Ti5O9. In a second aspect, solid, shaped and fired fibers of Ti4O7 and Ti5O9 are made by firing extruded fibers from mixtures of TiO2.
