ABSTRACT:
A process for preparing a powdered product with superior homogeneity. A precursor solution is prepared by adding an additive selected from glycerol, glyceryl nitrate, polyglycerols, glycols or polyglycols with a concentration of 0.1-2.0 percent by weight to an aqueous solution of metal nitrate. The precursor solution is atomized into droplets and thereafter heat treated to obtain a powdered product of particles.
