Abstract
In this paper the electric behaviour and other structural, physicochemical and micro structural characteristics of four commercial varistors of differ ent makers were studied and compared with other three developed prototypes. The comparative results permitted to know the causes of the prototypes low performance, concluding that with a better control of the raw materials pr ocessing, the pre-forming and the thermal treatment, in conjunction with an increase of the Sb2O3 quantities in the prototype M2, a varistor with a go od performance may be produced.
