Influence of Adding SiC on Microstructure and Electrical Properties of ZnO-based Nanocomposite Varistor

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-graine...

influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistor

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 ...

The Effects of Electrical Degradation on the Microstructure of Metal Oxide Varistor

-In this paper, the findings from systematic experiments with the purpose to determine the degradation effect of single and multiple current pulses on the microstructure of the Metal Oxide (MO) varistor are described. Six distribution class varistors from one manufacturer were used in these experiments. The first part of the paper describes the electrical condition after application of single a...
