摘要
以氧氯化锆为原料,采用硬脂酸溶胶凝胶工艺制备出了纯氧化锆及钇稳定的氧化锆(YSZ)纳米晶。用傅立叶变换红外光谱(FT-IR)和热重(TG)、差热(DTA)分析仪对反应历程进行了分析,X射线衍射仪(XRD)进行物相分析及粒径计算,透射电镜(TEM)观察粒子形貌。结果表明,该工艺方法简单且制备的纳米晶颗粒均匀,分散性较好。
Nanocrystalme of zircoma and yttna-stabilized zircoma(YSZ) was prepared by stearic acid method from zirconyl chloride.The reaction process was investigated by Fourier transform infrared spectroscope (FT-IR),thermogravimetric analysis(TG),and differential thermal analysis(DTA).X-ray diffraction(XRD) was used to analysis the crystalline phase and to calculate the diameter of particle,and transmission electron micrograph (TEM) was used to observe the shape of particle.The results show that the method is simple and particles of zirconia and yttria-stabihzed zirconia (YSZ) prepared by this method have good homogeneity and dispersivity.
