主要产地红宝石的热处理工艺及其定量化检测进展

Progress in the Technology of Heat Treatment and the Quantitative Inspection of Ruby from Main Origins

随着现代科学的发展和市场需求的刺激,红宝石的热处理理论及改善工艺从火烧时代进入高科技领域,并在科学研究中显示为更强的区域化。目前普遍的热处理工艺都需从微量元素入手分析改善机制,根据其生长环境、化学成分、内部结构等的不同分类探讨热处理方案,处理方式的侧重点稍有不同。针对不同产地、不同典型特征的红宝石,国内外学者尝试了一系列针对性的改色工艺试验。而随着科学技术的日渐成熟和多学科研究技术的交叉应用,红宝石热处理工艺的定量化检测也日趋成熟。识别典型内含物并联合谱学、色度学的综合分析仍然是检测红宝石热处理(特别是低温热处理)的关键性证据和衡量改善效果的重要参数。

With the development of modern science and the stimulation of market demand, the heat treatment theory and improvement process of ruby have been involved from the time of burning to the time of the high tech, with stronger regional features in scientific research. To analyze the improvement mechanism, the paper started with the trace elements and probed the heat treatment schemes on the basis of different classifications in its growth environment, chemical composition and internal structure, which made the focus of treatment be slightly different. Domestic and foreign scholars have experimented on the rubies of typical characteristics from different producing places with a series of targe ted process tests of color alteration. On the other hand, with the maturing of science and technology and the cross application of multidisciplinary research, the quantitative detec tion on ruby heat treatment process becomes more and more ripe. The outcome with the comprehensive analysis method that includes identifying typical inclusions, combining spectroscopy, and colorimetry is still the critical evidence for the detection of ruby heat treatment（especially low temperature heat treatment） and an important parameter to measure the effect of improvement.
