Electrophoretic Formation of Zinc Oxide Based Ntc Rsistors (RESEARCH NOTE)

Fine zinc oxide particles were electrophoretically deposited on alumino-ferro-chrome substrates. The deposition was carried out in a cylindrical ZnO/acetone electrophoresis cell. The deposits were dried and sintered at ۱۰۳۰³C in air. The process resulted a porous polycrystalline ZnO cladding over the alloy core. Comb shaped silver electrodes were formed and fired at ۳۵۰³C. The variation of device resistance vs. temperature was studied in air in the range of ۱۰۰ - ۲۵۰³C. The NTC of resistivity at ۱۰۰³C and the activation energy of carrier generation was found to be ۴.۰% K-۱ and ۱.۱eV respectively.
