Abstract
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 pressin g and sintering at 1550 degreesC/2 h. X-ray diffraction measurements were p erformed 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, i s valid for thoria-yttria solid solutions. (C) 2001 Elsevier Science B.V.
