摘要: In this work we have tackled the feasibility of colored oxides in Bi 2 O 3 -R system as ecological inorganic pigments. We prepared by solid state reaction mixed (Bi ) 1-x (R x , R: Nd, Sm and Dy, with nominal compositions: x=0.2 0.5; Sm, x=0.4; x=0.35. The obtained orange 0.6 (Sm 0 4 0.65 (Dy 0.35 present f.c.c. fluorite-type structure. 0.8 (Nd 0.2 oxide consists a mixture two phases which δ-Bi Bi-Sr-O-type structures 900-1200°C temperature range. synthesis composition 0.5 greenish sample higher neodymium content. This presents R 5 12 -type Diffuse reflectance data color coordinates suggest that 0.4 are expected to be promising candidates new
