摘　　要：通过Leica偏光显微镜、傅里叶红外光谱仪、气相色谱仪等仪器表征,分析了天然水晶和不同矿区的普通硅石矿中金属杂质元素和气液包裹体的含量,探讨了适合微波-酸蚀工艺去除石英砂中的气液包裹体的矿物特征。结果表明:杂质元素含量较低、气液包裹体含量较少、液相水填充度较高的石英矿源,适合采用微波-酸蚀工艺去除石英砂中的气液包裹体;所选用的5个矿样中,马达加斯加矿区的石英砂中金属元素杂质含量接近一级天然水晶,并且其气液包裹体含量较少,气液包裹体中气液比较高,适合采用微波-酸蚀工艺去除。Through the characterization of Leica Polarizing Microscope, Gas Chromatography and Fourier Transform Infrared Spectroscopy （FT-IR）, analyzed the content of metal impurity element and gas-liquid inclusions in natural crystal and ordinary silica mine of different mining areas, and investigated the characteristics of silica mine which was suitable for microwave-acid erosion process to remove gas fluid inclusion in quartz sand. The results showed that the silica mine of low content of impurity, less content of gas-fluid inclusion and high water filling degree was appropriate for the microwave-acid erosion process. And in the selected five samples, the content of metal element impurities in quartz sand from Madagascar was nearly close to the primary natural crystal, and it had less content of gas-fluid inclusion and high gas-liquid ratio, which was suitable for the microwave-acid erosion process to remove.
