dc.description.abstract | ZnO based varistors are widely used for overvoltage protection in many electrical and electronic circuits, at
voltages ranging from a few to over a million volts. By careful control of the microstructure, through nano-
structuring by chemical routes, it should be possible to produce varistors with high breakdown voltage (
V
c
),
as this is proportional to the number of active grain boundaries in the sintered body. This property is
particularly important for the production of the small-sized varistors needed for modern electronic
instruments such as tablet computers and mobile phones. The current review will outline the recent
advances in the chemical processing (
e.g.
sol
?
gel, combustion synthesis plasma pyrolysis, micro-emulsion
synthesis and precipitation routes) of varistors from ZnO nanomaterials and the properties of these
materials. Uncontrolled grain growth at higher temperature is highlighted as a major challenge for
obtaining desirable electrical properties for nano-varistors. Various novel sintering techniques such as
step-sintering, spark plasma and microwave sintering methods are expected to deliver a varistor with
controlled grain growth and optimum electrical characteristics | en |
