Mixing 4% of porcelain powder and different quality fraction metal-oxides(SnO2
SiO2
Al2O3) into WO3-based and heating for 1h at stable 600℃
the heating type thick film combustible gas sensitive sensor can be manufactured.Based on the experiments and adopting steady voltage measuring method
the relationship between the heat voltage and the sensitivity of sensor is studied.Experiment results show that the sensitivities of WO3-based combustible gases sensitive sensor are improved by doping different quality fraction metal-oxides with the tepefaction power at 600mW.
