Abstract:
An inductively coupled plasma torch for vaporizing a molten salt containing a volatile component and a refractory component which comprises:a substantially cylindrical shaped outer member defining an axis; a substantially cylindrical shaped inner member coaxially positioned inside said outer member to establish a space for holding a fluid coolant therebetween, said inner member having an inner wall defining a chamber extending along said axis; an induction coil, positioned in said space between said inner member and said outer member and submerged in said fluid coolant, for radiation of r.f. power into said chamber; and a means for injecting the molten salt into said chamber for direct interaction with said r.f. power to create a carrier gas of the volatile component during initial vaporization of the molten salt for subsequent use of the carrier gas in vaporizing the refractory component.
