Fe_2O_3基陶瓷的气湿敏特性

Gas and Wet Sensitivity of the Fe 2O 3 Based Ceramics

论述了由不同制备工艺获得的Ｆｅ２Ｏ３陶瓷及各种添加剂下表面羟基和吸附氧的形成和性质，分析了表面羟基和吸附氧的酸碱性对气湿特性的影响。

Formation and property of surface hydroxyde and adsorbed oxygen on Fe 2O 3 ceramics with and without various additives obtained by various preparing techniques was discussed. The effect of acidity and alkalinity of surface hydroxyde and adsorbed oxygen on the gas and wet sensitivity was analysed.
