Cu-P (Copper-Phosphorus) Editor The Cu-P phase diagram is redrawn from [Hansen] (0 to 25 at.%) and [72Uga] (25 to 100 at.%). The Cu-Cu3P partial system is a simple eutectic. Liquidus temperatures were measured by [05Gui], [06Hio], [07Hey], and [33Lin]. The solidus curve of (Cu) was measured by [40Cra] and the solubility of P in (Cu) is estimated to be 3.5 at.% at the eutectic temperature of 714 C. The eutectic temperature was reported to be substantially different (up to ~100 C) by other investigators ( see [Hansen]). [37Mer] determined the solvus curve by lattice parameter measurements. The melting point of Cu3P is 1022 C [72Uga], in good agreement with 1023 C reported by [32Mos]. The phase diagram of the Cu3P-P partial system was determined by [72Uga] under constrained pressure conditions. The P vapor pressure is 15 atm at the melting point of CuP2. The existence of CuP2 was also reported by [39Har], [65Olo], [ 68Gor], and [82Mol]. The liquidus between CuP2 and P could not be measured due to high vapor pressure. Because the stability of various allotropic forms of P is not well-defined, the P-rich end of the phase diagram is not drawn. In addition, [82Mol] reported the existence of another compound, Cu2P7, in this range, which is not shown in the phase diagram. The crystal structure data are from [38Ste] (Cu3P), [65Olo] (CuP2), and [82Mol] (Cu2P7). 05Gui: L. Guillet, Genie Civil, 47, 184-188 (1905) in French. 06Hio: A.H. Hiorns, J. Soc. Chem.
