<p><P>PROBLEM TO BE SOLVED: To provide a method for producing zirconia fibers having excellent heat resistance and a small fiber diameter. <P>SOLUTION: This method for producing the zirconia fibers having an average fiber diameter of 50 to 1,000 nm and a fiber length of≥100μm comprises a step for dissolving a fiber-forming solute in an aqueous solution containing a water-soluble zirconium chloride dissolved therein, a step for spinning the aqueous solution containing the fiber-forming solute by an electrostatic spinning method, a step for obtaining a fiber structure accumulated on a collection substrate by the spinning, and a step for calcinating the accumulated fiber structure. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
