SEMICONDUCTORIZATION OF THE GRAINS IN TiO_2 CERAMIC
TiO_2压敏陶瓷晶粒半导化

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
