摘要
ThO2:x mol% Y2O3 (x = 0, 3, 6, 9 and 12) ceramic powders have been prepared by the citrate technique. Dense specimens have been obtained after pressing and sintering at 1550 degreesC/2 h. X-ray diffraction measurements were performed in the sintered pellets for structural phase analysis and lattice parameter determination. The experimental results suggest that an empirical equation, similar to the equation proposed for zirconia-yttria ceramics, is valid for thoria-yttria solid solutions. (C) 2001 Elsevier Science B.V.
