Microstructure and electrical characteristics of shock-consolidated ZnO-Bi2O3-MnO2 bulk
Youngkook Kim, Seong-Seung Kang, and Chai-Bong Lee


Consolidation of ZnO-Bi2O3-MnO2 powders was performed using an underwater shock compaction technique. The compact exhibited crack-free formation, and interparticle bonding between ZnO powder particles was observed. Microstructure and peak broadening behavior of the compact was investigated by FE-SEM and X-ray analysis. Electric resistance was measured using the Nyquist plot method. The broadened peaks formed by lattice defects were detected in X-ray analysis, and high electric resistance of Mega ohms due to crystal deformations by shock energy was confirmed.
