Zr(OCH2CH2O)2 was directly synthesized by using HOCH2CH2OH solution in a 50 mL-flask.The nano-ZrO2 powder was prepared by a direct sol-gel process of the above solution and the following dryness at 400 ℃ for 2 h.The product Zr(OCH2CH2O)2 was characterized by FT-IR

Raman spectra and NMR.XRD and TEM were used to investigate the structure of nano-ZrO2.The experiments show that Zr(OCH2CH2O)2 contains-OCH2CH2O-roup and can prevent hydrolysis and calcinations of the precursor from gathering.The nano-ZrO2 with the diameter of 15~35 nm was obtained in a high purity.
