in this research the influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistors were investigated. sic was added with amounts of 10-0 mass% to zno-based varistor composition. it is found that sic allows reaching to high threshold voltage with formation of fine-grained zno.another important effect of adding sic is formation zn2sio4 (willemite) on the ...

SiC was added with amounts of 10-0 mass% to ZnO-based varistor composition. It is found that SiC allows reaching to high threshold voltage with formation of fine-graine...

The results of measuring the resistivity thin-film structures Ti|Si@O@Al|Ti and Ti|LiCoO2|Ti by electrochemical impedance spectroscopy (EIS) cyclic voltammetry (CV) are presented. It was found that, according to EIS data, resistance is three orders magnitude higher than CV which due nonohmic nature metal-semiconductor junction varistor effect. shown that Ti-LiCoO2 contact ohmic, while nonlinear...

Noise has been used as a diagnostic tool of surge arrester varistor structures comprising of ZnO grains of various type and size. The physical and electrical properties of the measured samples have been described. In the experimental study, the applied measurement system and the results of noise measurements for the selected structures of varistors designed for the continuous working voltage 28...
