Ca-Sn (Calcium-Tin) Editor The Ca-Sn phase diagram is redrawn from [Hansen] and is based on the thermal and microscopic investigation of [26Hum]. The Ca used in their study was impure, and therefore, the phase diagram is considered tentative. The melting point of Ca was raised for consistency with [Melt]; the various melting and invariant temperatures were also raised by ~5 to 20 C. [66Mur] reported some solubility of Ca in Ca2Sn. The existence of Ca31Sn20 was reported by [77For].- P.R.S. 26Hum: W. Hume-Rothery, J. Inst. Met., 35, 319-335 (1926). 33Zin: E. Zintl and S. Neumayr, Z.
