Before shaping, Lu 2 O 3 powders doped with different ZrO 2 concentrations were synthesized by a simple combustion method and milled. The shaped green bodies were sintered at 1850°C for 6 h in vacuum. The transmittance and microstructure of the resultant ceramics were characterized by spectrophotometer and SEM . The effects of ZrO 2 concentration on the microstructure and optical property of transparent Lu 2 O 3 ceramics were evaluated. When doped with 5 at.% ZrO 2 , the Lu 2 O 3 ceramic showed the best optical transmission and the in‐line transmittance reached 70% in the visible spectral region. The addition of ZrO 2 was found effectively to prohibit grain growth and to remove residual pores.
