CGO) is used in this experiment.The CGO powder is sintered in air at 1 450 ℃ for 4 h after dry-pressing.The sample sintered under this sintering system basically meet the requirement of the sensitive material for oxygen sensor after its physical properties being analyzed.A new type of limiting current oxygen sensor with a dense diffusion barrier is prepared.According to the test
the sensor shows better limiting current property in higher oxygen volume fraction
and a related theoretical model is established
which can explain the relationship between the limiting current and the oxygen volume fraction of this sensor well.
