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.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 4830 °C: 6 C carbon (diamond ...
Above the graphite–diamond–liquid carbon triple point, the melting point of diamond increases slowly with increasing pressure; but at pressures of hundreds of GPa, it decreases. [14] At high pressures, silicon and germanium have a BC8 body-centered cubic crystal structure, and a similar structure is predicted for carbon at high pressures.
In absence of oxygen, e.g. in a flow of high-purity argon gas, diamond can be heated up to about 1700 °C. [48] [49] At high pressure (~20 GPa (2,900,000 psi)) diamond can be heated up to 2,500 °C (4,530 °F), [50] and a report published in 2009 suggests that diamond can withstand temperatures of 3,000 °C (5,430 °F) and above. [51] Diamonds ...

Melting points (in blue) and boiling points (in pink) of the first eight carboxylic acids (°C). For most substances, melting and freezing points are approximately equal. For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2]
