Mechanism of Effect on BaTiO_3-Based Thermal Sensitive Resistance Ceramics

The mechanism of the semiconducterization or barium titanate ceramics crystal and the effect of PTC on BaTiO3-based PTC ceramics by the introduction of some additive and impurity ions, have been described. According to the principle of ionic chemical valence control and the structural characteristics or crystal boundary for the reasonable selec- tion of raw materials, and the effective control of the process technology, we give orientation in the sensitivity of the composition of production process, and in the stability of product quality.
