摘要

利用XRD研究了采用不同稳定剂制备的钛酸铝陶瓷在 85 0℃还原气氛下（铝熔体中）的热分解率。发现采用复合稳定剂Y2 O3 +MgO制备的钛酸铝陶瓷材料在铝熔体中 85 0℃ /5 0 0h的热分解率仅为 4.3 %

具有良好的热稳定性。利用该材料所制备的低压铸造陶瓷升液管

在 70 0～ 90 0℃的热稳定性优良

可稳定运行 60d不破坏

Abstract

The thermal decomposition behaviors of aluminum titanate ceramic prepared with various stabilization additives at reducing atmosphere at 850 ℃（aluminum melt） were studied by means of XRD. The thermal decomposition rate of the aluminum titanate ceramic prepared with Y 2O 3+MgO as stabilization additive was only 4.3% in aluminum melt at 850 ℃ for 500 hours. The aluminum melt feeding pipe prepared with ceramic materials can be well operated at 700～900 ℃ for 60 days in low pressure die casting.
