Progress in study on nonlinear electrical transporting theory of varistor;

Effect of nano-sized TiO_2 doping on ZnO varistor;

Preparation of doped ZnO nano-powders and ZnO varistors by different methods;

Then ZnO varistors were prepared at different sintering temperatures.

Using zinc nitrate, urea and additives as raw materials, doped ZnO nanopowders for varistors were prepared by the self-propagating combustion method.

The research progress of Microwave-sintered Zinc oxide varistors was reviewed.

Lightning Protection Discussion on Life of Piezoresistance used in Power System;

The optimum position and arrangement of four piezoresistances on rectangle diaphragm and the optimum dimension of the piezoresistances were determined.

A Study of the Piezoresistor Used as Low Vacuum Gauge;

The impulse voltage caused by intrusion oflightning wave into low voltage power cable laying down inpower dispatching center building is researched when thefactors, such as different cable wiring schemes, whether thepiezoresistors are installed and the number of piezoresistorgroups, are respectively considered.

ZnO varistors of large current high ( and high voltage.;

Superposition sintering to control Bi_2O_3 vaporization in ZnO varistors

This paper presents a theoretical investigation on the coprecipitation coating doping by ammonia for preparing ZnO varistor ceramic powders.
