Abstract:
As the increasing requirement of compact and light electronic and electrical system, especially for high energy density storage system, the development of high dielectric permittivity materials becomes one of critical solutions. Among all materials, barium titanate materials have been found to be a promising ceramic capacitor dielectric system, like BaTi1-xHfxO3 material and BaTi1-xSnxO3 material. However, to search the optimal composition, mass samples are needed by the traditional method of exhaustion, which increases the cost of work. In order to access the optimal composition of high permittivity efficiently, a machine learning prediction is employed to the searching process in Sn/Ca doped barium titanate ceramics. The machine learning prediction is iteration between theoretical predictions and experiment data. According to our prediction, the searching result shows Ba0.86Ca0.14Ti0.86Sn0.14O3 has the peak values of dielectric permittivity with ϵr=2.0×104 at T=13°C. As a result, sample preparation number reduces to 5.5% compared with the traditional method of exhaustion. In addition, good temperature stability has been found in Ba0.86Ca0.14Ti0.86Sn0.14O3 because of the relaxor behavior. © 2018 IEEE.
