Abstract

High purity ZrCl4 (25 to 200 ppm of metallic impurities) can be readily prepared in simple apparatus by thermal decomposition of alkali chlorozirconate fused salts at 500° to 600°C and at atmospheric pressure. Suggested phase diagrams for the systems NaCl-ZrCl4 and KCl-ZrCl4 are presented.
