| Abstract: Nanopowder of Y1.84La0.16O3 was prepared by oxalate co-precipitation method. The powder was characterized by TG-DTA, XRD and TEM. The results show that the precursor is Re2(NO3)2(C2O4)2·2H2O (Re=Y, La), and the Y1.84La0.16O3 nanopowders produced by calcining the precursor at 1 000 ℃ for 4 h are 20～40 nm spherical particles and well dispersed. The powders were with high sintering activity and could be fabricated to transparent ceramic without additive at 1 450～1 550 ℃ in H2 atmosphere for 3 hours. The total transmission of the transparent ceramic could reach 80%. |
