The coating method includes the steps of dissolving coating precursors in a solvent to form a precursor solution adding with mixing a miscible diluent to the precursor solution to form a coating solution admixing solid particles to the coating solution to form a coating slurry, with the particles surrounded with the coating solution spraying the coating slurry to form droplets containing at least one particle passing the droplets through a drying zone where the droplets are dried and form dry particles coated with a coating material formed from the coating precursors heat-treating the coating material on the particles emanating from the drying zone to remove volatile matter on the coating material, to improve integrity of the coating material andor to effect another objective and collecting dry coated particles.
