Cl-Cu (Chlorine-Copper) P.R. Subramanian and D.E. Laughlin No equilibrium phase diagram is available for the Cu-Cl system. The equilibrium phases reported are (1) the liquid, L; (2) the A1 fcc terminal solid solution, (Cu); (3) the B3 zinc blende-type cubic intermediate phases, CuCl II, stable up to 407 C at atmospheric pressure; (4) the B4 wurtzite-type hexagonal intermediate phase, CuCl I, stable between 407 C [68Rap] and its melting point (422 C) [79Kir] at atmospheric pressure; and (5) the monoclinic intermediate phase, CuCl2, stable up to 630 C. The melting point of pure Cu is 1084.87 C [Melt]. The triple point and boiling point of (Cl) are -100.97 C and -34.05 C, respectively. [64Val] reported two pressure-induced transitions at 42 and 55 kbar, respectively, in CuCl. [61Edw] showed two pressure-dependent transitions, one originating at ~54 kbar, and the other at ~100 kbar. [68Rap] showed the existence of two triple points at 1.2 kbar, 451 C and 3.8 kbar, 436.5 C, respectively, and involving the CuCl I-CuCl III-L and CuCl II-CuCl I-CuCl III equilibria, respectively. The CuCl II-CuCl III-CuCl IV triple point of 64 kbar at 215 C is an estimate from [68Rap]. 22Wyc: R.W.G. Wyckoff and E. Posnjak, J. Am. Chem. Soc., 44, 30-36 (1922). 38Han: J.D. Hanawalt, H.W.
