ELECTRICALLY CONDUCTIVE FIBERS OF Ti4O7 AND Ti5O9

摘要

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 gre en 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.
