Effect of Atmosphere on CaZrO3/ZrB2 Composite Sintering
-
摘要: 氧化物與非氧化物的燒結,合適氣氛的選擇特別重要.CaZrO3與ZrB2是化學性質截然不同的2種化合物,經過熱力學分析,在所考慮的各種氣氛中,這2種化合物高溫時只有在Ar氣保護的中性氣氛中才能穩定存在.實驗也證實了熱力學分析的可靠性.Abstract: The effect of atmosphere on the sintering of CaZrO3/ZrB2 composite has been studied in three kind of atmosphere. Thermodynamic analysis has indicated that at high temperature both CaZrO3 and ZrB2 thermodgnamic relation would be stable only in Ar atmosphere. The experimental results have verified the reliability of the above thermdgnamic analysis.
