Development of high performance titanium dioxide (Ti02) based varistor materials demands binders to improve its physical properties which will ultimately enhance its electrical performances. The material used for ceramic based varistor should exhibit good mechanical properties. As for desired mechanical properties, porosity should be minimal, high fued density, high sintered strength and small average grain size are desired. In this paper effect of PV A (binder) on Ti02 was investigated and its influence on physical, mechanical and microstructure was observed. The binder was added during ball milling and then followed by the shaping and sintering process. The samples were characterized by evaluating fued density, hardness, compressive strength and microstructure. Our studies revealed that varistor disc with higher density, hardness and strength can be produced with the use of binder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
