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...

A Comparative Study of Thermal Conductivity in ZnO- and SnO2-Based Varistor Systems

We performed a comparative study of electrical and thermal properties of ZnOand SnO2-based varistor. The electrical properties of commercial ZnO-based varistor are equivalent to that found in SnO2-based varistor system. In spite of this, the SnO2 showed a thermal conductivity higher than commercial samples of ZnO-based varistor, which allied with its simpler microstructure and lower dopant conc...

Synthesis, Structure, Spectroscopy and Photocatalytic Studies of Nano Multi-Metal Oxide MgO∙Al2O3∙ZnO and MgO∙Al2O3∙ZnO-Curcumin Composite

   The mixed metal nanocomposite MgO∙Al2O3∙ZnO has been prepared by coprecipitation method. The product was characterized by XRD. The average particle size was found to be 34.89 nm from XRD data. SEM and SEM-EDS were studied for evaluating surface morphology and elemental composition. The FTIR spectrum of prepared mixed metal nanocomposites MgO∙Al2O3</s...
