Abstract
The ammonium chloride route to anhydrous rare-earth metal trichlorides, RECl3, is a two-step procedure consisting in, firstly, the (dry or wet) synthesis of a complex chloride, (NH4)3 RECl6 (t≈ 220°C) and, secondly, its decomposition either directly (small RE, t≈ 425°C) or via the intermediates (NH4)2 RECl5 (large RE, t≈ 385°C) and NH4RE2Cl7 (medium-size RE), respectively.
