摘要
通过Ａｌ２Ｏ３ＣＮ２系统的热力学计算，表明ＡｌＮ氮化温度应控制在１６００～１７５０℃。提高氮化温度、降低Ｎ２分压有利于生成Ａｌ４Ｃ３。脱碳温度应控制在５５０～６５０℃，以避免粉末氧含量的增高。
The thermodynamic calculation in the system of Al 2O 3 C N 2 shows that the temperature of nitridation should be controlled at between 1600℃ and 1750℃. Increase of temperature or decrease of N 2 partial pressure is favorable for the formation of Al 4C 3. The temperature in burning off the excess carbon should be controlled at between 550～650℃,in order to prevent the increase of oxygen content in the powder.
