莫来石对氧化铝基陶瓷型芯的高温抗变形能力的影响

Effect of Mullite on High Temperature Anti-deforming Capability of Alumina-based Ceramic Core

研究了在不同状态下,氧化铝基陶瓷型芯中莫来石的含量及其微观结构对氧化铝基陶瓷型芯高温抗变形性能的影响。结果表明,氧化铝基陶瓷型芯具有优良的热强性能归因于高温下莫来石柱状晶群的存在。

The effect of mullite content and microstructure on high temperature anti-deforming capability of alumina-based ceramic core was investigated. The results show that superior heat intensity properties of alumina-based ceramic core resulted from crystal group of mullite at high temperature.
