摘要: EuSO4不同于一般的二价稀土化合物,对水、空气稳定,便于实用。已报道的EuSO4制备均为湿法[1~4]。EuS4的干法合成的结果有助于考察湿法合成中水对EuSO4的结构与性质的可能影响。

关键词: EuSO4干法合成, 晶体结构

Abstract: EuSO4 was prepared by a dry way reaction for the first time as follows:EuCl2 (s)+HgSO4(s) EuSO4(s) 3×10-4Pa.Ar/773K.72h→EuSO4+HgCl2(g) was obtained, orthorhombic barite structure (Prima, Z=4), with a=838.69± 0.15pm, b=534.95±0.09pm, c=688.18±0.13pm. Atom positions of Eu,S and O were proposed, resulting in a set of calculated intensities coincided well with the observed.

Key words: EuSO4 synthesis, Crystal structure
