The equilibrium boundary between graphite and diamond
Abstract
The equilibrium boundary between diamond and graphite has been determined over the temperature interval 1100°C–1625°C. A piston-cylinder apparatus and a ‘zero-friction’ cell were used. Pressures were computed by force/area measurements and are independent of any calibration points. Visual observations of diamond dissolution or diamond growth were used in fixing the position of the boundary. Our newly determined boundary has the equation P(kbar) = 19.4 + T(°C)/40 kbar. Corrections for the effect of pressure on the emf of thermocouples have been made. Our newly determined boundary is almost coincident with the 1961 boundary published by the General Electric Company (Bundy et al., 1961)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
