“…This is owing to most of the oils are nonpolar . Loss tangent for microwave insulator is less than 0.1, whereas loss tangent for microwave absorber is more than 0.1. From Table , all oils exhibit loss tangent of less than 0.1 except for rosemary, peppermint, and palm shell oil.…”

“…At this frequency materials heat differently as a function of conductivity, permittivity and permeability (Saxena and Chandra, 2011). For this reason, inhomogeneous materials are not heated evenly by the microwaves, and must therefore be stirred or fluidized (George et al, 1994).…”

“…In this process, there is volumetric absorption of electromagnetic energy, which is transformed into heat because of microwave radiation. Core heating, utilization of energy supplied up to 80-90% and heating rates could be induced up to several degrees in a second, 19,20 which are the additional advantages over conventional sintering methods.…”

We have investigated the structure, dielectric and electrical properties of lead-free polycrystalline (Na 0:47 K 0:47 Li 0:06 ) NbO 3 ceramics as a function of temperature and frequency in order to understand the intrinsic contribution of grain/bulk and grain boundary effects toward the dielectric response as well as the electrical conduction mechanism in the samples fabricated by microwave sintering method. X-ray diffraction analysis exhibits perovskite structure with orthorhombic symmetry, which is well supported by the Raman spectroscopic analysis. A minor secondary impurity phase of tungsten bronze structure was observed for samples sintered at 1050 C, which gets weaker for samples sintered at 1150 C. Dielectric permittivity was enhanced by 50%, although there was a reduction in the dielectric loss by about 50% at Curie temperature (450 C) for samples sintered at 1150 C. Complex impedance spectroscopic analysis indicated non-Debye-type dielectric relaxation present in the samples, and this phenomenon followed thermally activated process related to hopping mechanism. Nyquist plot showed the negative temperature coefficient of resistance, characteristic of the samples.
