摘要：

In this paper, the preparation of gamma-Fe2O3 and gamma-Fe2O3-TiO2 thick films by screen printing method is presented and their sensitivities and selectivities to acetone, ethyl alcohol, ammonia and LPG are studied. The experimental results revealed that the gas sensitivity is strongly related to operating temperature, film composition and gas type.
