The results show that BZN_based low symmetry β phase is an incongruent compound, dissociating to form α phase and liquid phase with absorption of heat, at peritectic temperature of 1 100 ℃.
研究表明 ,低对称 β相是异成分熔融化合物 ,在 110 0℃吸热分解为α相与液相 ;在自然冷却时 ,发生转熔过程 ,α相转入熔融液相中 ,析出 β相 ;在淬火冷却时 ,液相中析出BZN系立方萤石相 。
BZN-based phase is an incongruent compound, decomposing into phase and liquid phase when absorpted with heat at the incongruent melting point (peritectic temperature) 1 100 .
结果表明：α相是同成分熔融化合物，熔点１１９０℃；β相是异成分熔融化合物，在１１００℃吸热分解为α相与液相。
