Y2Zr2O7 transparent ceramic was successfully fabricated from combustion-synthesized powders. The as-prepared Y2Zr2O7 powders were characterized by XRD, FE-SEM, TEM, and BET area. After high-energy ball milling, the porous structure of the powder was destroyed. The Y2Zr2O7 transparent ceramics were obtained by sintering the ball-milled powders at 1850 degrees C for 6 h in vacuum. Ball milling of the as-burnt powders was found to play a key role on the in-line transmittance of the resultant ceramic.
