摘要
本文利用化学沉淀法制备了Ｅｕ（ＯＨ）３超微粒样品，将样品在不同温度下于空气中热处理２小时，得到一系列Ｅｕ２Ｏ３超微粒样品，利用Ｘ－ｒａｙ衍射仪对样品的结构和粒度进行了测试分析，发现Ｅｕ２Ｏ３超微粒样品相对于大块同类物质发生了“晶格膨胀”．
Eu (OH )3 ultrafine particles were prepared with precipitation method,Eu2O3 ultrafine particles with various grain sizes were obtained by treating Eu(OH )3 ultrafine particles at various temperature in air.The grain size and structure of EuiO,ultrafine particles was measured by X--ray diffraction and the lattice expansion was found.
