                         nanoparticulate zirconia (3Y-TZP) ((tetragonal zirconia

                         parts of the Brazilian satellites to act as mechanical shield for 
                         micrometeoroid and space debris impacts. The ceramic composites 
                         were obtained by mixing dispersed suspensions of alumina powders 
                         and 18.5 wt % of nanoparticulate zirconia, compacted with 
                         isostatic pressure and sintered at 1550 °C. After sintering, the 
                         ceramic composite was analyzed by SEM, X-ray diffraction and 
                         subjected to 4 points mechanical bending test. The microstructure 
                         analyses were performed and rupture stress values with Weibull 
                         distribution. The results were compared to previous works obtained 
                         after mechanical mixture of same powders. The results analyses 
                         showed that the greater homogeneity distribution of zirconia 
                         nanograins on alumina matrix contributes to increased fracture
