Abstract: A plasma torch for vaporizing a molten salt containing a volatile component and a refractory component injects the molten salt into a device that includes a cylindrical shaped outer member and a cylindrical shaped inner member coaxially positioned inside the outer member to surround a chamber. An induction coil positioned between the inner and outer members generates r.f. power which is initially used to vaporize the volatile component of the molten salt to create a carrier gas having an elevated temperature. The carrier gas then heats the refractory component, under an increased vapor pressure from the carrier gas. This action, in turn, breaks down the refractory component of the molten salt into fine droplets. These fine droplets are maintained in the chamber until they also vaporize. In one embodiment, the plasma torch includes a nozzle for spraying droplets of the molten salt into said chamber.
