Uranium tetrachloride (CAS NO.10026-10-5) is used as feed in the electromagnetic isotope separation (EMIS) process of uranium enrichment.
Uranium tetrachloride (CAS NO.10026-10-5) is produced commercially by the reaction of carbon tetrachloride with pure uranium dioxide UO2 at 370°C.
Reported in EPA TSCA Inventory.
Probably a poison. When heated to decomposition it emits toxic fumes of Cl−. See also URANIUM.
