The effect of method of preparation, including the traditional ceramic method and several sol-gel methods have been studied on the molar composition (ZrO2)0.92(Y2O3)0.04 and (ZrO2)0.82(Y2O3)0.04(Pr2O3)0.05 praseodymium doped samples. Powder fired at 500ºC was sieved at 60 μm, uniaxialy pressed and fired at 1.600ºC for 2h. The resulting compacts were characterised by XRD, SEM-EDX, density measurements, toughness strength and Vickers microhardness. The results indicate that colloidal samples stabilises tetragonal zirconia polymorph showing the best densification and electrical conductivity behaviour, praseodymium addition stabilises cubic zirconia improving the microhardness and densification of the material.<br><br>Se ha estudiad...
