The structure, thermal expansion and electrical conductivity of Ce 0.8 (Gd 1-x Bi x ) 0.2 O 1.9 (x = 0.1-0.5), prepared by coprecipitation were investigated. Ce 0.8 (Gd 1-x Bi x ) 0.2 O 1.9 ceramics was sintered in the range of 1350-1450 • C for 6 h; the bulk density of Ce 0.8 (Gd 1-x Bi x ) 0.2 O 1
