DOI: 10.1007/s10854-017-7632-9
Abstract: ZnO–V2O5–Mn3O4–Bi2O3 (ZVMB) varistor ceramics were sintered at a low temperature range of 800–875 °C, and the microstructure, electrical properties, dielectric characteristics, and DC-accelerated aging behavior were systematically investigated. Analysis of the microstructure indicated that the average… read more here.
