摘要
应用富里叶变换红外谱仪研究了三个含碱绿柱石样（包括原样与热处理样）。将３４３５ｃｍ－１宽吸收带归属于与铁离子成键的水。谱图表明隧道水的大量脱去是在８００℃以上的温度开始的，对于富碱样品，更可能是在１０００℃以后开始。隧道中碱金属离子的阻塞作用是造成绿柱石隧道水难以失去的重要原因。
The infrared spectra of 3 alkali-bearing beryl samples are measured in the range of stretching and bending modes of water.The 3440cm-1 absorbance is caused by the water molecules which are bound to iron ions.Most of water molecules are expelled at temperature higher than 800℃,and maybe higher than 1000℃ for alkali-rich samples.The plugging effect of alkali is the important reason why releasing volatiles from the channels requirs such high temperatures.
