The present invention relates to a powder of molten grains of yttria-stabilised zirconia, said grains having the following chemical analysis, in weight percent on the basis of the oxides: Zr0 2 + HfO 2 : remainder up to 100%; 11.8% ≤ Υ 2 O 3 ≤ 18.6%; 0.07% ≤ Αl 2 Ο 3 ≤ 1.8%; TiO 2 ≤ 0.6%, provided that 0.5 < Al 2 O 3 ; 0.3% ≤ TiO 2 if 0.6% < Al 2 O 3 ; and other oxides: ≤ 2.0%. |
