High temperature NTC BaTiO3-based ceramic resistors
چکیده انگلیسی

In our research it was firstly found that BaTiO3 materials doped BaBiO3 compounds only showed NTC effect in wide temperature scale. The effect of the composition on the microstructure and electrical properties of BaTiO3-based NTC thermistors was studied. Major phases present in the sintered bodies were the solid solutions of BaTiO3 compounds with a perovskite structure and BaBiO3 compounds with a monoclinal structure. The average grain size of the samples increased with increasing BaBiO3 contents. It is apparent that the samples' ρ450 and B450 / 600 constant decreased with an increase in BaBiO3 content.
