Other printed: yPtSn	0.86 unspecified	2073.15		model	[2] Grolier 2008	p. 7 report	The claimed strong bends [38] are puzzling since the present model exhibits an even stronger associate formation at 1800 ◦ C with a maximum value of yPtSn = 0.86 at xPt = 0.5 compared with the lower maximum value of yPtSn = 0.67 given in [38].
