There seems to be an error in the Specific heat of Flibe. Other, more primary references give it as about 2,4 kJ/kgK. http://www.psfc.mit.edu/library1/catalog/reports/1980/80rr/80rr012/80rr012_full.pdf — Preceding unsigned comment added by Michel Lamontagne (talk • contribs) 19:34, 22 March 2014 (UTC)

Finally it wasn't an error just a confusion between specific heat capacity and volumetric heat capacity. Added a line to clarify.

Toxiticity

Beryllium compounds are notorious for their extreme toxiticity. For other chemicals, toxiticity is usually discussed in a dedicated section. 188.195.171.124 (talk) 07:18, 1 March 2024 (UTC)

Eutectic vs Molar

The intro mentions these two, which seem to be slightly different mixtures of LiF and BeF₂? I missed this subtle distinction upon the first few readings, so I wish there was more text highlighting the difference between them, because it seems to make all the difference in the world. The melting point is 99° different, and, I guess, I'd always assumed that a eutectic mixture is a stoichiometric compound. Guess not.

• "The 2:1 molar mixture forms a stoichiometric compound, Li2[BeF4] (lithium tetrafluoroberyllate), which has a melting point of 459 °C (858 °F), ..."

• "The eutectic mixture is slightly greater than 50% BeF2 and has a melting point of 360 °C (680 °F). ..."

Maybe this should be two subsections, maybe named 'lithium tetrafluoroberyllate' and 'eutectic mixture'? Other mixtures are possible, probably not useful?

Also, that 50%, is that volume or mass or molar? OsamaBinLogin (talk) 19:51, 23 June 2025 (UTC)

Changing link for lithium tetrafluoroberyllate

Currently, there's no page for lithium tetrafluoroberyllate as of writing, but there is a page for the tetrafluoroberyllate anion. Would it be worth it to replace "lithium tetrafluoroberyllate" with "lithium tetrafluoroberyllate" for the time being, or wait until a page is created for the former?
