文摘

Co2SnO4 doped SnO2 based ceramics may be materials used as medium voltage varistors. As spinel addition increases, so does the densification and grain size. As spinel addition increases, the electric field, the barrier height decreases. The Co2SnO4 spinel phase was synthetized in the laboratory to be used as dopant.
