| 摘 要： | 红-黄色翡翠是否经过热处理,其价值相差悬殊。随着市场对红-黄色翡翠的需求增加,鉴别其是否经过热处理是目前宝玉石鉴定的难点和热点问题。通过加热实验,利用红外光谱测试技术对加热前、后的红-黄色翡翠样品的红外光谱进行对比分析。结果表明,加热前、后的红-黄色翡翠样品的红外光谱具有不同的特征,主要表现为硬玉结构中OH的四组吸收峰强弱的变化:(1)吸收峰的强变化是在3 000～4 000 cm-1之间的峰型从加热前呈U型到加热后呈V型;(2)吸收峰的弱变化则是谱线略有改变,出现3 622～3 628 cm-1或3 670 cm-1附近的吸收峰,这些特征可作为红-黄色翡翠是否经过加热处理的辅助性诊断指标。

| Abstract: | The value of red-yellow jadeites is very different depending on whether they have been processed with heat treatment.With an increasing demand for red-yellow jadeites,it has been a key as well as difficult issue to distinguish whether the jadeites are experienced heat treatments or not.In this paper,the heat treatment experiments are carried out on the red-yellow jadeites,and the infrared spectra of the jadeites before and after heat treatment are also compared.The results show that different spectral chara... |
