摘要

The YCrO3 negative temperature coefficient (NTC) ceramics have been successfully fabricated through a field-assisted sintering technique with a low sintering temperature and a short sintering period. The orthorhombic perovskite YCrO3 powder synthesized from a Pechini method was formed at a temperature range of 780-800 C through a decomposition of YCrO4. The as-sintered YCrO3 ceramics had a relative density of 97.6 %. The values of ρ 25, ρ 600, B 25/600 and activation energy of the YCrO3 NTC thermistor were 1.21 × 106 Ω cm, 7.26 × 102 Ω cm, 3,358 K, 0.293 eV, respectively. Such ceramics could be used as the potential candidates for NTC thermistors in a wide temperature range from 25 to 600 C.
