The Influence of Bi2O3 and Sb2O3 on the Electrical Properties of ZnO-Based Varistors
This work presents a study of the influence of both Bi content and Sb/Bi ratio on the electrical characteristics of a commercial-type ZnO varistor. In contrast to previous studies two nonlinear coefficients, t...

Modified Citrate Gel Techniques to Produce ZnO-Based Varistors (Part II—Electrical Characterisation)
The electrical characteristics of doped ZnO pellets prepared by novel, modified citrate gel routes and the conventional mixed oxide route were compared. The mixed oxide route produced rather inhomogeneous mate...

Modified Citrate Gel Techniques to Produce ZnO-Based Varistors (Part I—Microstructural Characterisation)
Two novel chemical processing routes were developed for the production of ZnO-based varistor powders and compared with the conventional mixed-oxide route. The central idea behind the new techniques was to sepa...

Macroscale production of microsystems
Much effort has been exerted by many researchers in the development of techniques for the production of microsystems and components. The current array of micromachining techniques has largely been developed fr...
