| Abstract: | ZrO2-Y2O3 series ultrafine powder had been prep ared by subzero treatment,the particle size was 10～15 nm.By isostatic compactin g and sintering,the compact zirconia ceramic element was produced.Ultrafine plati num powder,special platinum paste for electrode and chloroplatinic acid were ado ped respectively to make electrode.Electrical conductivity of the ceramic elemen t had been tested using alternating current bridge method,the composition of ZrO 2-Y2O3 ceramics for oxygen sensor was also determined on the basis of the above results. |
