摘　　要：采用TGA-16型高温热重分析仪,研究高温下氮氧化物耐火材料氧化增重情况,通过测量材料在规定升温条件下的氧化增重曲线和材料的表面积,测算材料起始氧化温度、最大氧化速率温度以及单位面积的氧化增重,以表征材料的抗氧化性能。In this paper,TGA-16 high-temperature thermogravimetric analyzer is used to study the oxidation-induced weight gain of NOxrefractories at high temperatures.By measuring the oxidationinduced weight gain curve and the surface area of the material under the specified heating curves,the initial oxidation temperature,the maximum oxidation rate temperature and the oxidation-induced weight gain per unit area of the material are calculated to characterize the oxidation-resistant performance of the material.
