Fe2O3-TiO2-K2O复合氧化物体系结构与湿敏性能
摘要:
Fe2O3是一种湿敏材料[1,2],由于其阻值高,感湿特性差,在Fe2O3中掺入K2CO3降低了材料阻值,改善了感湿灵敏度.

Structure and Humidity Sensitivity of Complex Oxides Fe2O3-TiO2-K2O
Abstract:
A series of sintered complex oxides were prepared from T-Fe2O3 and K2CO3 (in molar ratio of 95:5) with addition of TiO2. The XRD results showed that addition of TiO2 increased the porosity of the mixed oxides and eliminated the formation of U-K2O and KFe11O17 phases, which usually cause the hysteresis of such a material.
