Fourier transform infrared spectrometer (FTIS) and polarizing microscope are utilized to analyze the water molecule content in the gas-liquid inclusions in quartz sand and the micro-morphology change laws of gas-liquid inclusions before and after microwave heating. The experimental results show that when the quartz sand is heated to 600℃ under microwave, cracks or micro-cracks of gas-liquid inclusions appear at the interface, which causes the (OH)-water in the crystal lattice to transform into smaller liquid inclusions. Most gas-liquid inclusions can be removed by continuously increasing the microwave intensity so that the temperature of the quartz particles is as high as 900℃.Experiments show that the establishment of mathematical model can better reflect the heating behavior of quartz particles in the microwave field, and provide an effective theoretical basis for further study of the influence of these factors on the relationship between internal pressure and tangential tensile stress of inclusions, such as gas-liquid inclusion filling degree, fluid density, homogenization temperature, inclusion radius .
