LIU Fengmin, QUAN Baofu, CHEN Lihua, et al. Influence of BaTiO3 on the properties of SnO2-based CO gas sensors[J]. 2003, (2): 5-7. DOI: 10.13873/j.1000-97872003.02.002.
?The temperature coefficient of SnO2based CO gas sensors is adjusted by adding BaTiO3 into sensors materials
longterm stability of gas sensors is improved.Each property of the sensors is related with property and content of BaTiO3.When BaTiO3 whose mass fraction is 2% containing YCl3 whose mole fraction is 0.4% is added into the sensor materials
sintered temperature of the sensors is hightened
sensitivity of the sensors towards C2H5OH is also decreased
and longterm stability of the sensors is improved.
