The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

Francium's melting point was estimated to be around 8.0 °C (46.4 °F); [11] a value of 27 °C (81 °F) is also often encountered. [8] The melting point is uncertain because of the element's extreme rarity and radioactivity ; a different extrapolation based on Dmitri Mendeleev 's method gave 20 ± 1.5 °C (68.0 ± 2.7 °F).
