Abstract
:
This report contains the final laboratory results conducted Alyainat titanate barium atoms grafted holmium (Ho). We have been preparing the way these samples are then studied the chemical thermal resistivity in the case of direct current (DC), and studied the static permittivity in the case of alternating current (AC) at different temperatures That the samples grafted atoms holmium showed aspiring factor of resistance thermal positive (PTCR) in the case at a temperature of 120 C and the opposite of barium titanate clean which did not show the phenomenon of the PTCR (as explained in the first report), but the resistance of the samples during the high temperature is different. The static permittivity showed unusual behavior in the articles of the Ferro-electric in both its fresh and the restaurant. The possible interpretation of these results using granular Mozj Inter-granular model proposed by Heywang and which was developed later by Jonker
