摘要
锆石热处理工艺技术已有数百年的历史,通过不同温度下惰性环境、氧化、还原、氧化+还原等气氛热处理工艺能够改善大部分锆石颜色、透明度、外观等物理性质,超高温热处理通过改变部分锆石的类型改变其宝石学性质。一般认为天然锆石的红褐色系列色调由色心导致,天然或处理蓝色锆石由离子致色,Fe3+可以使锆石显示黄色调。研究锆石热处理及其原理有助于找出热处理锆石与天然锆石的鉴别特征,但这方面研究还不够深入。
It has been hundreds of years for zircon heat treatment, the color, transparency, appearance and other physical properties of zircon are improved under different tempera- ture with oxidation, reduction or inert environment, also the gemology characters change accompany with the zircon's type changing under ultra-high-temperature. It is generally believed that zircon's hue with reddish-brown comes from the color center, while some ions induce blue (by Fe or U) and yellow tone (by Fe3+ ). Researching the zircon heat treatment and its principles will help to identify the heat treatment zircon and the natural zircon, which is not deep enough now.
