Key words: PTCR effect, BaTiO3-ceramics, Heywang-Jonker-Daneils model, fractal correction, phase transition 1. INTRODUCTION The positive temperature coefficient of electrical resistivity (PTCR or PTC) effect, in this case, is a jump in the resistivity of many orders of magnitude in a certain temperature range of the poly-crystalline semiconducting n-doped BaTiO3 across the Curie point (T0 ~ 130oC), respectively, in the paraelectric-ferroelectric phase transition (tetragonal-cubic structural change) (see [1-4]).	cache/fuelectenerg-7485.pdf	txt/fuelectenerg-7485.txt
