碳化硅中在氧气气氛下的稳定性检测方案(热重分析仪)

ANO26CeramicsExcellence in thermal analysis and calorimetry Stability of SiC under O2 Experimental： Sample analyzed with platinum suspension without DTA. Sample mass ： 639 mg. Carrier gas ： oxygene.The sample is heated rapidly at 1150℃ and maintain ed during 14 hours at this temperature. Conclusion： After a mass increase during the first hours， a regular mass loss is then observed. Instrument： SETSYS Evolution TGA-150℃ to 2400℃ www.setaram.com - sales @setaram.com 样品重量：639 mg载气：氧气样品迅速升温至1150度，并且在这样的高温中保持14个小时。实验结论：在开始的一个小时，随着质量的增加，可以观察到有规律的质量损失。
