溶胶共沉淀过程pH值的确定
Determination of pH in sol-coprecipitation process
【摘要】 研究了如何确定溶胶共沉淀过程中最佳pH的范围。结果表明,用NH4 HCO3作ZrOCl2·8H2O与Y(NO3)3混合溶液的沉淀剂,进行溶胶共沉淀时的最佳pH值范围是5~6。
【Abstract】 In this paper, it is studied that how to determine the range of optimal pH value in sol-coprecipitation. The results show that then NH4HCO3 is used as precipitant for mixed solution of ZrOCl2. 8H2O and Y(NHO3)3 to carry on the sol-coprecipitation, the range of optimal pH value is 5~6.
