| 摘 要： | 稀土铝酸盐发光材料在使用过程中和金属铁接触并发生相对运动则会出现色泽变暗现象,影响其产品外观及发光亮度.通过化学分析、原子吸收分光光度法、X-射线衍射、扫描电镜等方法对稀土铝酸发光材料与金属铁作用过程和机理进行研究,阐明了其色泽变化的原因,得出铁被氧化,氧化铁因冲蚀磨损掺杂到稀土铝酸盐粉末中导致粉末色泽变化.

| Abstract: | During Service,if the Lanthanon aluminates luminescent powder surface contacts and does relative movement with metal,it will be nigrescent.Chemic analytical tool,Such as atomic absorption spectrophotometric,X-ray diffraction and Scan electron microscope are used to analyse the nigrescent powder.The nigrescent mechanism is that erosion makes Fe2O3 mixed in the lanthanon aluminates powder. |
