Physical characterization of Titanium Dioxide based varistor materials doped with Cobalt Oxide
TiO2 varistor material acts as surge arrestors against transient voltages in electrical and electronic equipments. However, the enhancement of properties as a surge protector is very much dependent on the types of dopants being used. Not only that, the microstructure and enhanced mechanical characte...
