Characterization and performance evaluation of zinc oxide varistor blocks processed by latex binders

The processing of ZnO varistor has a long route with numerous contributing variables. The binder plays an important role in the fabrication of this electro-ceramic device. Higher density and strength of a green body are critical not only for handling at its green state but also to avoid the causes o...
