ABSTRACT:
A process for distilling zirconium sponge in an iron containing vessel at a temperature sufficiently low to preclude iron contamination of said sponge is disclosed. A distillation temperature near about 934.degree. C. is sufficiently low to minimize iron contamination while being sufficiently high to cause sintering of the sponge to a degree that subsequent comminution does not produce excessive fines.
