Abstract :
This paper illustrate the effects of BaTiO3 (barium titanate) particles sintering on dielectric properties at a poliolefinic adhesive who have inserted this particles. The dielectric characteristics analyzed are the real and imaginary part of permittivity and dielectric losses of the poliolefinic adhesives with sintered particles (PO-S) and the poliolefinic adhesives with non-sintered particles (PO-NS). The measurements are done in a range of frequency between 0.1 Hz to 10 MHz and for a variation of temperature from 30 oC to 150 oC, with a step of 10 oC. We also analyzed the effect of Curie temperature of samples, to understand the structure effect on dielectric properties. Samples structure was analyzed with a X-ray difractometer.
