测试纳米晶体SnO2 、ZnO材料的热稳定性对于提高气体传感器的可靠性是十分重要的。本文对纳米晶体SnO2 、ZnO分别在 80～ 370K和 2 98～ 1773K温区进行了低温热容和热稳定性测量。利用热重分析仪 (TGA)进行低温量热预处理 ,并且利用差式扫描 量热仪 (DSC)对纳米晶体热稳定性进行了考察
Testing the thermal stability of nanocrystalline SnO2 and ZnO materials is very important for improving the reliability of gas sensors. In this paper, the low-temperature heat capacity and thermal stability of nanocrystalline SnO2 and ZnO were measured in the temperature range of 80 ~ 370K and 2 98 ~ 1773K, respectively. The thermal gravimetric analysis (TGA) was used to pretreat the low temperature calorific value, and the thermal stability of the nanocrystal was investigated by differential scanning calorimeter (DSC)
