A process for producing ultra-fine ceramic particles in which droplets are formed from a ceramic precursor mixture containing a metal cation, a nitrogen-containing fuel, a solvent, and an anion capable of participating in an anionic oxidation-reduction reaction with the nitrogen containing fuel. The nitrogen-containing fuel contains at least three nitrogen atoms, at least one oxygen atom, and at least one carbon atom. The ceramic precursor mixture is dried to remove at least 85 weight percent of the solvent, and the dried mixture is then ignited to form a combusted powder.

A process for producing ultra-fine ceramic particles, comprising the steps of: (a) forming droplets of a ceramic precursor mixture containing a metal cation, a nitrogen-containing fuel, a solvent, and an anion capable of participating in an anionic oxidation-reduction reaction with the nitrogen containing fuel, wherein said nitrogen-containing fuel is of the formula R.(HA)a, wherein: 1. a is an integer of from 0 to 2, 2. HA is selected from the group consisting of HNO3, HCl, HBr, HI, H2SO4, H2O, and CH3COOH, 3. R is of the formula [Figure] wherein: (a) R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, alkyl of from 1 to about 4 carbon atoms, and phenyl; (b) b is an integer of from 1 to 2, c is an integer of from 0 to 2, and a plus c is at least 1, and 4. R contains at least four hydrogen atoms, provided that the ratio of hydrogen atoms to oxygen atoms in R is at least 3; (b) removing at least about 85 weight percent of the solvent from the droplets of the ceramic precursor mixture to form particles comprising the metal cation, the anion, and the nitrogen-containing fuel, thereby forming dried particles; and (c) subjecting said dried particles to a temperature of from about 500 to about 600 degrees centigrade and an atmosphere with a relative humidity of less than about 60 percent, thereby causing said dried particles to react in an explosive manner.
