Abstract

The objective of this work is to study the influence of sintering temperature and additive content on the electrical characteristics and microstructure of ZnO based varistors with Bi/sub 2/O/sub 3/ (always present), Sb/sub 2/O/sub 3/, Co/sub 3/O/sub 4/, MnO/sub 2/ and Cr/sub 2/O/sub 3/ as additive oxides. The influence of sintering temperature and additive content on the electrical characteristics of ZnO based varistors without Bi/sub 2/O/sub 3/, but with additives from the rare-earth oxide series such as Eu/sub 2/O/sub 3/, La/sub 2/O/sub 3/, Pr/sub 6/O/sub 11/ and Ho/sub 2/O/sub 3/, is also studied. Procedures and results are presented in detail.

Distribution of chemical elements in a zinc oxide ceramic for varistors

Journal Article Glot, A B - Inorg. Mater. (Engl. Transl.); (United States)

The authors used x-ray spectral microanalysis to investigate the distribution of Zn, Bi, Sb, Co, and Mn in a ceramic for varistors based on ZnO with additives. Specimens of composition (mole %) 97.5 ZnO, 1 Sb/sub 2/O/sub 3/, 0.5 Bi/sub 2/O/sub 3/, 0.5 Co/sub 3/O/sub 4/, and 0.5 MnO/sub 2/ were prepared by sintering under oxidative conditions. X-ray spectral microanalysis was carried out with a Cambridge Stereoscan S4 scanning electron microscopy with intersection of the specimen surface by the electron beam and superposition of the obtained distribution of the intensity surface region under conditions of secondary electron emission and alsomore »« less
Advanced metal oxide varistor concepts. Final report

Technical Report Philipp, H R ; Mahan, G D ; Levinson, L M

Zinc oxide varistors are ZnO-based ceramic semiconductor devices with highly nonlinear current-voltage characteristics similar to back-to-back Zener diodes but with much greater current, voltage, and energy-handling capabilities. Zinc oxide varistors have proven useful in a variety of applications, particularly as high-quality voltage suppression devices for the protection of ac and dc electric power transmission systems against the effects of transient overvoltages due to switching surges and lightning strikes. In the work described in this report, we have chosen to study simple varistor systems that use Bi or Pr as the varistor-forming additive and Co or Mn as the varistor-performance ingredient.more »« less
Sol-gel process doped ZnO nanopowders and their grain growth

Journal Article Xueya, Kang ; Tiandiao, Wang ; Yin, Han ; ... - Materials Research Bulletin

The doped ZnO nanoparticles are prepared by a sol-gel method. These ZnO nanoparticles provide ZnO-based ceramic varistors displaying superior varistor properties--higher value of the nonlinear coefficient, lower leakage current, and higher critical electric field values--as compared to those of conventional samples. The present work has been aimed at studying the effect of processing variables such as sintering temperature and duration on the microstructure and grain growth of ZnO-Bi{sub 2}O{sub 3}-Sb{sub 2}O{sub 3}-MnO{sub 2}-Co{sub 2}O{sub 3}-Al{sub 2}O{sub 3} ceramics. The activation energy calculated is found to be 364 {+-} 24 KJ/mol for Bi{sub 2}O{sub 3}-Sb{sub 2}O{sub 3}-MnO{sub 2}-Co{sub 2}O{sub 3}-Al{sub 2}O{submore »« less

Effect of grain-size distribution on the barrier voltage of ZnO varistors

Journal Article Sung, Gun Yong ; Kim, Chong Hee ; Oh, Myung Hwan - Advanced Ceramic Materials; (USA)

To prove the discrepancy between the calculated barrier voltage and the measured barrier voltage resulting from the broad grain-size distribution, the microstructures and grain size distribution with relation to I-V characteristics of ZnO-Bi{sub 2}O{sub 3}-MnO and ZnO-Bi{sub 2}O{sub 3}-MnO-TiO{sub 2} systems sintered at various temperatures have been investigated. Two barrier voltages measured from the direct and indirect methods were compared as a function of the sintering temperature and the standard deviation of the average grain size. Regardless of the sintering temperature, the measured barrier voltages obtained from the direct method were 5 V at 10 {mu}A and 6 V atmore »« less

Aluminum doping studies on high field ZnO varistors

Technical Report Kimball, K M ; Doughty, D H

We have investigated the effect of Al doping on the physical and electronic properties of high field ZnO varistors. For this study, varistors containing 98.94 m/o ZnO, 0.25 m/o CoO, 0.25 m/o MnO, 0.56 m/o Bi/sub 2/O/sub 3/ and 0 to 200 ppM Al were prepared from powders obtained from solution precipitation techniques. Because of the amphoteric nature of aluminum oxides, precise control of pH and metal concentrations was necessary to assure complete incorporation of dopants. We observed inhibition of grain growth during sintering of varistor pellets at aluminum concentrations of 50 ppM and above. The measured electrical properties showmore »« less
