BaTiO3-based positive temperature coefficient of resistivity (PTCR) ceramics is an important group of thermal materials. With the requirement of unleaded electronic components, the development of high curie temperature lead-free PTCR materials is an inevitable trend. In the paper, an introduction to the characteristics and applications of PTCR materials was provided. The present research status of high curie temperature lead-free PTCR materials were also reviewed, including composition, donor and acceptor doping, as well as the mechanisms of PTCR effect. Finally, the future development of PTCR materials was expected.
