The structure water is dehydrated completely as the temperature is over 1,100 K, the characteristic peak (3,580 cm-1) of the structure water disappears completely, the characteristic peak related to Si-Onb stretching vibration becomes 855 cm-1, which shows that primary Q1 of the hemimorphite is returned to Q0 (i.e [SiO4] ), and which means that the hemimorphite is completely transformed to willemite.

当升温达1 100 K以上，结构水的特征谱峰(3 580 cm-1)消失，与Si-Onb对称伸缩振动对应的特征拉曼谱峰变为855 cm-1，这标志着异极矿原有的Q1结构已完全转变为硅锌矿的Q0结构([SiO4]结构)，也就是说异极矿已完成向硅锌矿的转变。关键词：异极矿；原位拉曼光谱；测试；相变；高温
