Abstract
In this study, a temperature stable high dielectric ceramic capacitor was made by compositional fluctuation control. Dielectric property was examined by controlling mixing method and volume fraction of PMN, 0.9PMN-0.1PT, and 0.8PMN-0.2PT, each of which is the relaxor material of-10°C, 50°C, and 100°C maximum of dielectric constant respectively. It shows the most temperature stable characteristic at the composition of 0.5:0.2:0.3 volume fraction when the mixing method is parallel. And it shows flat dielectric constant of 10,000 in the range of-10°C to 100°C.
