초록
Thick film formaldehyde (HCHO) gas sensors were fabricated by using La1-xSrxMO3 (M=Fe, Co, Mn) ceramics. Thepowders of La1-xSrxMO3 (M=Fe, Co, Mn) were synthesized by conventional solid-state reaction method. By using theLa1-xSrxMO3 (M=Fe, Co, Mn) paste, the thick-film formaldehyde sensors were prepared on the alumina substrate by silk-scren printing method. The experimental results revealed that La1-xSrxMO3 (M=Fe, Co, Mn) ceramic powder has aperovskite structure and the thick-film sensor shows excellent gas-sensing characteristics to formaldehyde gas (sensitivityof La0.8Sr0.2FeO3, S=14.7 at operating temperature of 150oC in 50 pm HCHO ambient).
