Analogy between mechanical and dielectric strength distributions in BaTiO₃ thick films prepared under the different processing conditions

Mechanical and dielectric strength were measured for three types of BaTiO₃ thick films prepared under the different processing conditions. In any case, Weibull moduli for both strength distributions were identical in each type of films, though they differed among three types. The results indicated that dielectric strength measurements is a promising alternative method to distinguish the structural reliability change as influenced by processing parameters before firing within the framework of the same fabrication method.
