Metal Oxide based Varistors are basically ceramics, acting as n ? semiconductors,
having a poly-crystalline and dense structure. The main application of these power
electronic devices is for construction of overvoltage protection equipment (for every
voltage level), because of some advantages like: an increased level of non-linearity
between the current and the voltage characteristic, a high energy adsorption capacity
and an excellent good response time, which make them ideal for protecting other
sensible electronic devices and circuits, as well as large segments of power lines. This
paper presents a new material and some manufacturing technology aspects for a Metal
Oxide Varistor based on a new mixture of oxides used in order to obtain a new ceramic
with higher non-linear electric properties. The two oxides involved are Cr2O3 and MnO2
as dopants or additives. All measurements of the electrical performances will be carried
out in relation with existing 5 dopants material.
