真空高温环境下AlN的热力学行为分析
Thermodynamic Analysis of AIN in Vacuum High-temperature Environment
摘要
Abstract
The thermodynamic stability of AIN was discussed in vacuum high-temperature environment by using the classical thermodynamics determination method GT ＜ 0. The thermodynamic calculations show that the decomposition temperature of AIN is 2708 K under standard conditions, and the decomposition temperatures of it in vacuum high-temperature environment are 1556 K, 1454 K, 1365 K when the vacuum degrees are 10-1 Pa,10-2 Pa,10-3 Pa. The stability of AIN increases with the degree of vacuum decline. To a certain degree, the results provide a new route for the usage of AIN in vacuum hightemperature environment.关键词
