摘要
水热法合成水晶与天然水晶的物理化学性质相似、内含物少见,常规检测方法无法鉴别。本论文采用德国布鲁克(Bruker)TENSOR27红外光谱仪测试分析,发现合成无色水晶以3585 cm-1谱带为特征; 烟水晶特征吸收峰在3300~3000 cm-1附近,而合成烟水晶位于3600~3300 cm-1附近; 合成黄水晶仅有5200 cm-1吸收峰,黄水晶不具有此特征吸收; 紫水晶具有5228 cm-1、4450 cm-1特征谱带,合成紫水晶在4000~3000 cm-1内有特征吸收峰;合成绿水晶仅有5200 cm-1吸收峰。
Abstract
Hydrothermal synthesis crystal and natural crystal has the same physical and chemical properties,rare inclusion.Conventional detection methods can’t identify.In this paper,using Infrared spectroscopy analysis,Synthesis of colorless and transparent crystals found in 3585 cm-1 band is characterized; Smoky crystals absorption peak at 3300-3000 cm-1,and the synthetic smoky crystals is located at 3600-3300 cm-1; Synthetic citrine have 5200 cm-1 absorption peak,citrine doesn’t have this characteristic absorption; There are 5228 cm-1,4450 cm-1 characteristic spectrum of amethyst,the synthesized have characteristic absorption peak in the 4000-3000 cm-1; Synthetic green crystal is only 5200 cm-1 absorption peak.
