Abstract
The invention relates to the coating of particles for use, for example, as inoculants in the metallurgical field. A fluidized bed of metallic-particles (e.g. Fe/Si, Fe/Mn of size range 50 .mu.m to 3000 .mu.m or higher) is contacted with a wash-coat comprising a suspension of a non-dispersible ceramic powder in a sol (e.g. a suspension of Al(OH).sub.3 powder in a boehmite sol). Subsequent controlled drying and firing produces a ceramic coating on the particles which has good adhesion and thermal stability and whose thickness and density can readily be controlled.
