Abstract
A fine particle manufacturing apparatus and a fine particle manufacturing method are provided. The apparatus includes a raw material supply part supplying a raw material; a plasma torch in which the thermal plasma flame is generated and the raw material supplied by the raw material supply part is vaporized by using the thermal plasma flame to form a mixture in a gas phase state; and a plasma generation part generating the thermal plasma flame inside the plasma torch. The plasma generation part includes a first coil encircling the plasma torch; a second coil encircling the plasma torch and disposed below the first coil; a first power supply part supplying a high-frequency electric current to the first coil; and a second power supply part supplying an amplitude-modulated high-frequency electric current to the second coil. The first coil and the second coil are arranged in the longitudinal direction of the plasma torch.
