PROBLEM TO BE SOLVED: To realize fine particles having high productivity, uniform particle size, high quality and a method for producing the same. In a method for producing fine particles and fine particles, a powder raw material is placed in a solvent and stirred to form a slurry 3a. Then, the slurry 3 a put in the raw material supply device 3 is sprayed into the plasma torch 2 to form droplets. The slurry formed into droplets is introduced into a thermal plasma flame 7 generated in the plasma torch 2 to evaporate the slurry to form a gas phase mixture. Then, the gas phase mixture obtained by evaporating the slurry is rapidly cooled in the chamber 4 to generate fine particles. [Selection] Figure 1 |
