Influence of BaTi Ratio on the Positive Temperature Coefficient of Resistivity Characteristics of Ca-Doped Semiconducting BaTiO sub(3) Fired in Reducing Atmosphere and Reoxidized in Air

The positive temperature coefficient of resistivity (PTCR) characteristics of donor-doped BaTiO sub(3) fired in a reducing atmosphere and reoxidized in air are investigated. The result reveals that conventional semiconducting BaTiO sub(3) ceramics fired in a reducing atmosphere and reoxidized at a l...
