【Abstract】 The effect of Fe³+-Mn⁴+ complex acceptor doping and sinter technology on electric properties of PTC ceramics based on BaTiO₃ was studied. In order to investigate the details of this effect, find an optimum formulation and an optimum sinter technique and modify the property of PTC ceramics, different quantities of acceptor doping and various sinter techniques were compared and a lot of data of the resistance at room temperature and the resistance ratio, R_max/R_min, were taken.更多还原
