Comparative Analysis of Adding Hydrogen Peroxide or Ethanol in Preparation of Zirconia Nano-Powder by Coprecipitation Methods

摘要

Zirconia precursor was prepared by adding hydrogen peroxide or ethanol in co-precipitation process from raw materials of ZrOC12·8H2O and ammonia,the zirconia powders were subsequently obtained by calcination of the precursor at 600 °C and ball milling.Through the analyzed by TG-DTA,XRD,SEM,the results show that by adding hydrogen peroxide or ethanol in co-precipitation process can reduce the produce of agglomerate.Ethanol and hydrogen peroxide addition on zirconia by co-precipitation for different reaction results were compared and analyzed.
