摘要
以ZrOCl2,Ca(NO3)2和NH3.H2O为原料,用液相化学共沉淀法制备(ZrO2)0.9-(CaO)0,1粉末,经过600℃热处理,用TEM观察形貌,BET测定粒子尺寸,XRD和Raman光谱分析相结构.结果表明:粉末样品的粒径为8.9nm,晶粒表现为0.5nm的立方相结构.
With zirconium oxychloride, nitrate of lime and amonium as the raw materials, nanometer-sized powder of （ZrO2）0.9-（CaO）0.1 was prepared by chemical coprecipitation method under the doping of nitrate of lime and 600℃ to calcine. The grain was tested by the TEM and BET analysis, and phase structure was analysed through XRD and Raman spectrum.All the results indicated that the powder＇s particle size is 8.9 nm and cubic crystal particle is 0.5 nm.
