Enthalpy of mixing printed: enthalpy of mixing	13.5 kJ/mol (basis unstated)	1773		experimental	[1] Rajkumar 2017 cites Saeed 2006 doi	p. 5 report	The enthalpy of mixing of the liquid at 1773 K by Saeed et al.20 shows a kink at about 4.5 and 98.5 at.% Ni which confirms the immiscibility. These experimental values were fitted by Saeed et al.20 to give a maximum value of +13.5 kJ mol1 at Ag-60 at.% Ni.
Enthalpy of mixing printed: enthalpy of mixing	16.77 kJ/mol (basis unstated)	1773		model	[1] Rajkumar 2017	p. 5 report	In the present work, the enthalpy of mixing of Ag-59.9 at.% Ni at 1773 K is maximum with a value of 16.77 kJ mol1.
