Predel and Vogelbein [41] used solution calorimetry at 1068 K and determined the enthalpies of formation of the ε-FeSb phase at 45 at.% Sb and at 43 at.% Sb to be about (2.999 ± 1.385) and -(0.044 ± 1.234) kJ/g atom, respectively.
Uncertainty budget
Components kept separate, in the value's unit (literature SCHEMA.md, UNCERTAINTY_CALIBRATION.md): effective = max(sqrt(max(printed, reading, method)^2 + composition^2 + conversion^2), scatter). The method floor is the robust between-study scatter of the method class in ORCHID (calibrated) or a documented prior; printed values and printed uncertainties are unchanged.
