Ni/Graphite/BaTiO3 PTCR Composites
Nickel/graphite/BaTiO3 PTC composites with lower room-temperature resistivity and higher resistance jump were fabricated by adding graphite and nickel powders into BaTiO3 PTC ceramics. Characteristics and conductive mechanism of the composites were discussed based on the experimental results.
