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 lanthanum nickelate powder was prepared by coordination-precipitation method. The structure and properties of the material were characterized by X-ray diffraction, TG-DTA and scanning electron microscopy. The research shows that LaNiO3 prepared by this method has the advantages of simple method, easy filtration and short preparation time.
