Abstract
Co-crystallization of neodymium and strontium sulfates was studied using powder X-ray diffraction, energy dispersive X-ray spectroscopy, and microscopy. High absorption activity of crystalline matrices, trigonal SrSO4∙0.5H2O and dehydrated monoclinic SrSO4, towards the isomorphic heterovalent inclusion of Nd3+ ions to give solid solutions stable in the absence of water was established for the first time. The unit cell parameters and the structural similarity of the solid solutions were determined. In a moist environment, solid solutions degrade within 6–10 h to give stable poorly soluble single compounds Nd2(SO4)3∙8H2O and orthorhombic SrSO4.
硫酸钕和硫酸锶在无钾离子情况下的共晶体化研究
摘要 利用粉末 X 射线衍射、能量色散 X 射线光谱和显微镜研究了钕和锶硫酸盐的共晶。首次确定了晶体基质（三棱 SrSO4∙0.5H2O 和脱水单斜 SrSO4）对 Nd3+ 离子的同构异价包合的高吸收活性，从而得到在无水条件下稳定的固溶体。确定了固溶体的单胞参数和结构相似性。在潮湿环境中，固溶体会在 6-10 小时内降解，生成稳定的难溶单一化合物 Nd2(SO4)3∙8H2O 和正方体 SrSO4。
