Fe^(3+)、Al^(3+)在非典型玻璃中的配位状态

The Coordination State of Fe^(3+),Al^(3+) Ions in Non—typical Vitreous Phase

本文采用穆斯堡尔谱,X射线荧光和红外光谱等分析方法,分别测定了非典型玻璃——液态渣玻璃体中Fe^(3+)、Al^(3+)离子的配位状态,分析了它们共存时产生的结构效应,以及对液态渣水硬活性的影响. 实验结果表明,Fe^(3+)、Al^(3+)在非典型玻璃体中,有四、六两种配位状态,且在Fe^(3+)、Al^(3+)共存时,Al^(3+)四配位的能力比Fe^(3+)强.

The coordination state of Fe^(3+),Al^(3+)ions in nontypical vitreous phase has been determined respectively by means of Mossbauer spectroscopy, fluorescence X-ray diffractometer and infrared spectroscopy. The structural effect induced due to the co-existance of these cations in the vitreous phase and the influence on the hydraulic activity of the granulated cinder have been discussed. The experimental results show that Fe^(3+),Al^(3+) ions in non-typical vitreous phase have tetrahedral and hexahedral coordinations, and when there are simultaneously Fe^(3+)and Al^(3+) ions, the ability to form tetrahedral coordination of Al^(3+) ions is stronger than that of Fe^(3+) ions.
