Abstract
Ba1-xSrxTiO3-based positive temperature coefficient resistance (PTCR) ceram ics were prepared by use of a vapor-doping method. When doped with Bi, the PTCR effect is improved; when doped with lead, however, the effect is weake ned. The different influences of Bi and Pb doping on the ceramic properties are discussed in terms of the defect chemistry.
