Abstract

BaCo_1/3Nb_2/30₃ ceramics, with a high density and a similar, high degree of 1:2 B-sitc cation ordering, exhibit very different quality factors, Q. The ceramics exhibit p-type behavior withhigher conductivity and lower Q for samples processed in O₂as compared with those processed in air. It is proposed that unavoidable Co lossduring high-temperature ceramic processing leads to type doping that mustbe compensated by oxygen vacancies to impede hole formation. The composition exhibiting only intrinsic conduction and optimized Q is not achieved withprocessing in atmospheric oxygen due to filling of oxygen vacancies and hole formation during cooling.
