Abstract
A process for producing ultra-fine particles of calcia-stabilized zirconia in which a precursor mixture (which contains from about 80 to about 96 mole percent of zirconium ion, from about 20 to about 4 mole percent of calcium ion, a nitrogen-containing fuel, and a solvent) is dried and then subjected to a temperature of from about 275 to about 750 degrees centigrade and an atmosphere with a relative humidity of less than about 60 percent, thereby causing the dried particles to react in a vigorous manner and to form a combusted powder.
