Introduction. Barium titanate (BaTiO 3) exhibits a positive temperature coefficient of resistance (PTCR effect). This effect involves a substantial non-linear change of resistivity with temperature around the Curie temperature ( TC) [1]. It was determined that compositional modifications of Sr +2, or Pb +2 for Ba +2 produce changes in the Curie ...

Above 120°C, barium titanate has a cubic structure. This means it is centro-symmetric and possesses no spontaneous dipole. With no dipole the material behaves like a simple dielectric, giving a linear polarisation. T C for barium titanate is 120°C. Below 120°C, it changes to a tetragonal phase, with an accompanying movement of the atoms.
