本文研究了微波法去除石英中流体包裹体的工艺，并采用正交试验研究了主要工艺因素对去除效果的影响。采用傅里叶变换红外光谱（FT-IR）、徕卡偏光显微镜和差热分析（DTA）对不同微波条件下的石英样品进行了表征。最后，采用X射线衍射（XRD）对石英样品的微观结构和表面形貌进行了表征。结果表明，去除包裹体的最佳微波频率为1900 W，最佳保温温度为1000 °C，最佳保温时间为1 h。此外，通过热重分析和X射线衍射确定了β-石英向α-石英的相变。
In this article, the technology for removing fluid inclusions in quartz by the microwave method was investigated, and the influences of the main technical factors on the removal efficiency were studied using the orthogonal test. The quartz samples under different microwave conditions were characterized employing Fourier transform infrared spectroscopy (FT-IR), Leica polarizing microscope, and differential thermal analysis (DTA). Finally, the microstructure and surface morphology of the quartz samples were characterized by X-ray diffraction (XRD). The results showed that the optimal microwave frequency, holding temperature and holding time for removing fluid inclusions were 1900 w, 1000 °C and 1 h, respectively. In addition, the phase transformation from β-quartz to α-quartz was determined by the thermogravimetric analysis and XRD.
