The gas sensing characteristics of heterocontacts are investigated. heterocontact, with added, showed selective gas sensing properties, while pure heterocontact showed higher sensitivity to than to . It is suggested that the presence of a second phase containing Na+ in ceramic is essential for selective gas sensing by a heterocontact.
