Thermal behavior of TeOx xerogel powder under different atmospheres

The DataSet contains the results of the thermal behavior of the TeOx xerogel powder measured under different atmospheres. The material was obtained by the sol-gel method.  The starting solution was prepared by mixing telluric acid (precursor) with thetraetylene glycol, water, and ethanol. The sol was obtained by vigorously stirring precursor solution at 50°C for 2h, then the temperature was raised to 75°C for the next 2h. The obtained gel was dried at 120°C under an argon atmosphere. 
Thermogravimetric analysis (TG) and Differential scanning calorimetry (DSC) measurements were carried out under argon atmosphere from 40°C to 910°C (with a heating rate of 5 °C/min) and under synthetic air atmosphere in the temperature range 40-500°C (with a heating rate of 10 °C/min) using Netzsch STA 449 F1.

本数据集收录了不同气氛条件下测得的碲氧化物干凝胶粉末（TeOx xerogel powder）的热性能测试结果。该材料通过溶胶-凝胶法（sol-gel method）制备：以碲酸作为前驱体，将其与四甘醇、水及乙醇混合配制得到起始溶液；将前驱体溶液于50℃下强力搅拌2小时，随后升温至75℃继续搅拌2小时以制备得到溶胶；最终所得凝胶在氩气气氛下于120℃进行干燥处理。
本测试采用耐驰（Netzsch）STA 449 F1型同步热分析仪，分别在两种气氛下开展热重分析（Thermogravimetric Analysis，TG）与差示扫描量热法（Differential Scanning Calorimetry，DSC）表征：其一为氩气气氛，测试温度区间为40℃至910℃，升温速率为5℃/分钟；其二为合成空气气氛，测试温度区间为40℃至500℃，升温速率为10℃/分钟。
