THE THERMAL DECOMPOSITION OF THE HEAVIER RARE EARTH METAL CHLORIDE HYDRATES

Journal Article · · J. Inorg. & Nuclear Chem.
The thermal decomposition of the 6-hydrates of europium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium chlorides was studied on the thermobalance. The 6-hydrates began to lose water of hydration in the 65 to 95 C temperature range. Because of the decreasing basicity of the methl ions, horizontal weight levels corresponding to the anhydrous metal chlorides were not found. Instead, the decomposition curves in the 200 to 265 C temperature range corresponded to the composition MOCl.2MCl/sub 3/. On increasing the temperature, these compounds decomposed to form the metal oxychlorides in the 360 to 425 C temperature range. (auth)
