Abstract
A powder formed of fused particles. More than 95% by number of the feed particles exhibiting a circularity of greater than or equal to 0.85. The powder contains more than 88% of a silicate of one or more elements chosen from Zr, Hf, Y, Ce, Sc, In, La, Gd, Nd, Sm, Dy, Er, Yb, Eu, Pr, Ho and Ta, less than 10% of a dopant, as percentage by weight based on the oxides. The powder has a median particle size Dof less than 15 μm, a 90 percentile particle size, D, of less than 30 μm, and a size dispersion index (D-D)/Dof less than 2. The powder has a relative density of greater than 90%. The Dpercentiles of the powder are the particle sizes corresponding to the percentages, by number, of n %, on the cumulative distribution curve of the size of the particles of the powder. The particle sizes are classified in increasing order.
