Relation Between Mechanical and Textural Properties of Dense Materials of Tetragonal and Cubic Zirconia

In the current paper we present a study of the sinterability of two zirconia (ZrO2) nanopowders with different content of yttrium oxide (Y2O3) 3 and 8 % tetragonal and cubic zirconia, respectively. After sintering between 900-1500ºC, the samples were characterized in terms of their density and poros...
