Abstract

A pilot plant producing 600 lb of zirconium sponge a week is described. It comprises on arc furnace to make zirconium carbide, a chlorinator producing raw chloride, a purification vessel to eliminate zirconium oxide and iron from this chloride, two reduction vessels, two vacuum retorts for salt separation, and a graphite resistor vacuum furnace to melt ingots. A layout of the plant, power consumption, operation schedules, and production costs are given.
