Microwave assisted radiant heating (MARH) is hybrid sintering technique, where conventional radiant heating is accompanied by precisely controlled different microwave power (Mw) percentages. Lead-free polycrystalline samples of (Ba, Ca) TiO3 BCT ceramics derived from hydrothermal process were synthesized by MARH technique. A systematic study has been carried out to examine the effect of different microwave power (Mw) percentages applied during MARH on the structure, dielectric and electrical properties of BCT samples. Room temperature X-ray diffraction pattern and Raman Scattering spectra revealed formation of single phase tetragonal structure for all the samples and tetragonality increases with increasing Mw power percentages. However, the dielectric permittivity shows maximum increment (ε′ ~ 16,000) for the samples sintered with 30 Mw power percentage. Impedance spectroscopic analysis suggested negative temperature coefficient of resistance (NTCR) behavior with non-Debye type dielectric relaxation. Electrical resistivity also increases with increasing Mw power percentages for all the samples. Samples sintered with 30 Mw power percentage exhibited enhanced dielectric and electrical properties.
