Europium chloride hexahydrate, molecular formula: EuCl3 · 6H2O, molecular weight: 366.32, gray or lavender crystals, easily soluble in water and ethanol, deliquescent, airtight preservation. Uses: Used in the manufacture of europium compound intermediates, chemical reagents and other industries.
Europium trichloride, chemical formula EuCl3. Molecular weight 258.32. Yellow needle crystals. Specific gravity 4.89. Melting point 850 ℃. Soluble in water and ethanol. From the interaction of europium oxide and hydrochloric acid, europium chloride hexahydrate crystals are first prepared, and then heated to 180~200 ℃ in a hydrogen chloride atmosphere. If anhydrous europium chloride is heated to 400~450 ℃ in a hydrogen stream, a colorless amorphous europium dichloride is formed.
