Major effects on varistor properties of ZnO–V2O5–MnO2–Nb2O5–Er2O3 ceramics with sintering changes
Source abstract
Abstract
Abstract The microstructure and electrical properties of ZnO–V2O5–MnO2–Nb2O5–Er2O3 (ZVMNE) ceramics were investigated at different sintering temperatures (875–950 °C). The average grain size increased from 4.3 to 9.2 μm with the increase of sintering temperature. The breakdown field decreased from 7095 to 1256 V/cm with the increase of sintering temperature. The ZVMNE ceramics sintered at 900 °C exhibited a surprisingly high nonlinear coefficient (63). The donor concentration increased from 3.09 × 1017 to 7.99 × 1017 cm−3 with the increase of sintering temperature and the barrier height exhibited the maximum value (1.21 eV) at 900 °C.
