EFFECT OF PRODUCTION CONDITIONS ON CHARACTERISTICS OF FINE PARTICLES BY SPRAY-PYROLYSIS

The effect of production conditions on the characteristics of fine particles with spray-pyrolysis, using several kinds of cobalt salt solutions whose cations were commonly Co2+, was preriously studied. The characteristics of the fine particles produced by spray-pyrolysis from four kinds of acetate-salt solutions were investigated in order to study the mechanism of formation of fine particles in more detail. Under the experimental conditions an anion of (CH3COO)- was fixed. The acetate ion had no significant effect on the characteristics of the fine particles, but the reaction temperature was an important factor in determining their characteristics.
