    Evolution of the internal structure and physical properties of Tongxin sandstone under high temperature by Guanghui Jiang, Jintao Wang, Jinhao Wen, Jinhao Wen, Xingzong Liu, Bangyong Yu, Bangyong Yu, Yihan Wang

    Published 2024-12-01
    “…Scanning electron microscopy was used to observe microstructural changes in the sandstone. After analysis, the evolution of the internal structure of Tongxin sandstone with heat treatment is categorized into three stages. (1) stable change Stage (20–450°C, 650–700°C): Dominated by dehydration and thermal stress, where pore and fracture structures develop slowly; (2) rapid change stage (450–550°C, 600–650°C): Dominated by the kaolinite dehydroxylation, leading to increased porosity but decreased average pore size; (3) intense change stage (550–600°C): Dominated by the quartz phase transitions, where the thermal stress generated by quartz phase transitions causes dramatic alterations in the internal structure of the sandstone. …”
