| Abstract: | Mixing 4% of porcelain powder and different mass fraction metal-oxides in WO3-based materials,and heating for 1 h at stable 600 ℃,the heating type thick film gas sensitive sensor was manufactured. The relationship between the heating power and the sensitivity of sensor,the responding and recovery time were studied by the static state voltage measure method. The results show that the different combustible gases sensitive sensors of WO3-base by doping can be develo-ped with 600 mW tepefaction power. |
| Keywords: | gas sensitive sensor WO3-based doping ion sensitivity |
