NOx sensor for exhaust gas, and process for producing the same
摘要
An NOx sensor is produced by sintering a plurality of columnar crystals of beta -type Nb2O5. The average value M of aspect ratios b/a (wherein a represents a width and b represents a length) in the columnar crystals is set in a range of 2.11<M</=5. The NOx sensor has a high sensitivity to NOx via an enhancement attained by control of crystal type and structure.
