摘要
用配位-沉淀法制备了片状镍酸镧粉末，通过X射线衍射、热重-差热分析及扫描电子显微镜等实验手段对材料的结构组成及性能进行了分析表征。研究表明用该法制备LaNiO3具有方法简单、易过滤、制备时间短等特点。
The powder LaNiO3 was prepared by coordination-precipitation method. XRD, TG-DTAand SEM were used to characterize the sample. The results show that this method for preparingLaNiO3 has some advantages over the solid-reaction method. It is simple, easy to filter andtime-saving.
