摘要
用DTA和x射线粉末衍射法研究EuI2-NaI和EuI2-LiI两个二元体系低压相图.EuI2-NaI二元体系相图为一简单低共熔相图,低共熔点为4O9℃,其低共熔摩尔组成为32%NaI;EuI2-LiI体系相图也为一简单低共熔相图.低共熔点为385℃,低共熔摩尔组成为68.5%LiI.
The EuI2-LiI and EuI2-NaI systems were studied by differential thermal analysis (DTA) and X-ray powder diffraction. The phase diagram of EuI2-LiI is eutectic one. The results show that the eutectic point is at 385 ℃with molar composition 68. 5% LiI. The phase diagram of EuI2(Nal is an eutectic point too, the eutectic point exists at 409 ℃with molar composition 32% NaI- In both two systems the crystal transitiori of EuI2 at 354 ℃ has been found.
