N2 - Many metals show the steep increase of their specific resistivity on melting. This phenomenon was applied for producing new PTCR materials in the Pb-TiO2 and Sn-TiO2 systems. The xPb-(100-x)Ti0.9Nb0.01O2 samples with x > 15 showed the steep increase of resistivity (PTCR properties) around 327°C, and it was noted that the temperature coefficient of resistivity below the PTCR temperature changes from negative to positive with increasing Pb content. The xSn-(100-x)Ti0.99Nb0.01O2 samples showed PTCR properties around the melting point of Sn (232°C), but PTCR properties are less significant than those observed in the Pb-TiO2 system.
