Abstract
BaTiO3 ceramics with a small amount of Bi4Ti3O12 were sintered at a lo w temperature of 1100 degrees C for 2 h. We report a high densificatio n of the system (BaTiO3 + xBi(4)Ti(3)O(12); 0.01 less than or equal to x less than or equal to 0.03) larger than 90% of BaTiO3 theoretical d ensity except for x = 0.01. We show the measured ac impendances of the samples at approximate to 500 degrees C using the complex plane plott ing technique. The results involving large differences between the mat erial resistance are discussed in terms of the final microstructure af ter the sample firing.
