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 ...

MICROSTRUCTURE, ELECTRICAL PROPERTIES AND PROCESSING DEPENDENCE OF CuO MODIFIED (Na0.52K0.48)NbO3 CERAMICS

The CuO modified (Na0.52K0.48)NbO3 (NKN) piezoelectric ceramics were prepared by a solid-state reaction method. On the one hand, CuO doping can improve the densification behavior and simultaneously promote the grain growth, however, has little effect on the Curie temperature. On the other hand, the mechanical quality factor Qm obviously increases, the dielectric loss tanδ decreases, and the pie...

Microstructure and Properties of Spark Plasma Sintered MoAlB Ceramics

Advisor: Bai Cui Molybdenum aluminum boride (MoAlB) is a ternary transition metal boride which has promising aeronautic and nuclear applications. It inheres excellent properties of the binary transitional metal borides (e.g., MoB, ZrB2) such as high melting temperature, high hardness, and thermal conductivity. Besides, MoAlB is superior to MoB because: (1) the Al element provides an oxidation r...
