Abstract
Abstract: Thick films of ZnO-based ceramic varistors prepared by tape casting technique typically show a poor electrical response that still limits their application as protective devices. The excessive volatilization of Bi2O3 during sintering at high temperatures, especially dramatic in the film geometry due to its high area-volume ratio, is found to be the origin of this poor electrical behavior. The problem is overcome by sintering the films in a controlled Bi-rich sealed atmosphere, leading to a high reliability and reproducibility in their non-linear response.
