The spray particles have an average circularity in a plan view of 0.85 or less. The spray particles preferably have an average circularity of 0.6 or more. The spray particles may include yttrium fluoride and an yttrium oxyfluoride
  • The sedimentation rate of the spray particles in a slurry for thermal spraying can be a value determined by measuring all the spray particles in accordance with the centrifugal liquid sedimentation method (JIS Z8823-1: 2001). The sedimentation rate can be a value determined by a centrifuge sedimentation/light transmission method with a particle size distribution/dispersion stability analyzer (manufactured by L. U. M. GmbH
