Enthalpy of mixing printed: ΔmixH	3.443 kJ/mol (basis unstated)	1273		experimental	[1] Chewvalier 1989 cites Predel 1971	p. 5 report	The enthalpy of mixing of Ge-Tl liquid alloys has been measured calorimetrically by Predel and Stein [21]: T = 1273 K, xT, = 0.202-0.896. Enthalpies are positive and show a maximum of 3443 J.

Version 1, machine-extracted: values were read by language-model readers constrained to quote their source and checked automatically, and the release was then audited on the printed pages by adversarial audits, an independent second review of fit-facing records and a preliminary human review of a frozen sample. Flags such as accepted and ESPEI-ready record screening results, not certification; known issues are listed in the release notes.
