Dependence of the properties of CoO-doped ZnO-Bi2O3 varistors on heating and cooling rates during ceramic processing

Dependence of the properties of CoO-doped ZnO-Bi2O3 varistors on heating and cooling rates during ceramic processing

The dependence of the properties of CoO-doped ZnO-Bi2O 3 varistors on heating and cooling rates during ceramic processing, was analyzed. varistors properties are dependent on dopant type and concentration, grain size, composition and distribution of intergranular phases, and ceramic processing condi...

Brown A.P. Milne S.J. The dependence of the properties of CoO-doped ZnO-Bi2O 3 varistors on heating and cooling rates during ceramic processing, was analyzed. varistors properties are dependent on dopant type and concentration, grain size, composition and distribution of intergranular phases, and ceramic processing conditions. At a temperature of 1000 °C, the highest brakdown fields, were observed by using heating rates of 10°C/min and /or slow cooling rates, 1 °C/min. A reduced grain size was responsible for the heating rate effect. The value of exponent of nonlinearity had a maximum value of 25, with a minimum value of 15 recorded for the fastest heating rate. 2014-08-30T03:24:00Z 2014-08-30T03:24:00Z 2004 Conference Paper 00222461 10.1023/B:JMSC.0000048755.88512.9d JMTSA http://www.scopus.com/inward/record.url?eid=2-s2.0-24144481810&partnerID=40&md5=74ee2c2784021e7c37c05f2ecb3e9ff7 http://cmuir.cmu.ac.th/handle/6653943832/6242 English
