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 ZrOC_(12)·8U_2O and ammonia, the zirconia powders were subsequently obtained by calcination of the precursor at 600℃ 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.
