Resumen
Single phase (Bi2O3)1-x(Y2O3)x samples with x = 0.15, 0.20, 0.25 and 0.30 were successfully synthesized via conventional solid state method at the calcination temperature of 800 °C for 16 h. These
samples crystallized in cubic fluorite structure, space group Fm-3m and lattice parameter of 5.527< a < 5.464 Å. (Bi2O3)1-x(Y2O3)x subsolidus system was thermally stable as no phase transition or
weight loss was discernible within the studied temperature. Dense samples were sintered by both Spark Plasma Sintering (SPS) and pressureless sintering. (Bi2O3)0.80(Y2O3)0.20 samples with relative
density higher than 94 % and different grain sizes were obtained.
