Abstract：
 In method for synthesizing zirconia nano wire, ZrOCl2.8H2O and H2C2O4.2H2O are used as raw material, the process includes the following steps: respectively preparing zirconium oxychloride (ZrOCl2) and oxalic acid (H2C2O4) aqueous solutions, under the condition of continuously stirring ZrOCl2 solution slowly adding H2C2O4 solution into the ZrOCl2 solution, then continuously stirring to obtain zirconium sol; then impregnating porous alumina membrane with zirconium sol for 10 min., pressing for 5 hr. at 1.3 MPa, taking out said membrane from sol, drying under the infrared lamp., and roasting for 5 hr, at 500 deg.C and normal pressure under the condition of argon atmosphere so as to obtain the zirconia nano wire array. Said method can synthesize zirconia nano wire whose diameter is 50-300 nano and length is 10 micrometers, and said product can possess extensive application range.
