Abstract

This dissertation is about the development of $BaTiO_{3}$-type PTC(Positive Temperature Coefficient) thermistor by composition method. PTC samples were fabricated after setting the experimental composition equation as $(Ba_{0.95-x}Sr_{0.05}Ca_x)TiO_3\;-\;0.01TiO_2\;-\;0.01SiO_2\;-\;aMnCO_3\;-\;0.2Nb_{2}O_{5}$ and their testing results were analyzed. a PTC thermistor, having the characteristics of relatively low resistance at room temperature and c and a good temperature coefficient, has been developed.
