Abstract:
      In view of the complexity of the preparation process and difficulty of the popularization and application of silica aerogel, current status of studies on different influencing factors in the stage of sol-gel, aging and drying was described in detail. And the application researches in aerospace, construction, medical, catalyst and other fields were summarized. Then on this basis, the future development trend of preparation and application of SiO2 aerogel were put forward.
