Abstract Donor doping was used to make the grains semiconductive for a TiO_2 ceramic.The resistivity of the grains was measured by means of strong current pulse method and highfrequency equivalent circuit method.The results show that Nb_2O_5 doping can considerabl

Key words: varistor grain semiconducting donor doping
