Abstract
A sublimer assembly vaporizes zirconium tetrachloride in a Kroll reduction process. A retort for vaporizing the feed has a sidewall extending from a bottom wall with a peripheral heater adjacent to the sidewall and an internal heater extending through the retort. Substantial contact between the feed and the surfaces of the internal heater and retort sidewall is maintained so that the vaporization rate tends to cycle and the time required to vaporize the feed may be substantially reduced.
