Talk:Lead-bismuth eutectic

Hyphenated?

Hi. Should this be "lead-bisumth eutetic"? The current one lacks the hyphen, but I suspect it should have one. Thanks, William Pietri 15:47, 14 September 2006 (UTC)

Probably no. It isn't a specific term, just lead-bismuth eutectic solution, general terms. Sorry, somehow misread that - yes. And Lead-bismuth eutectic, to be exact. CP/M ^comm |Wikipedia Neutrality Project| 16:13, 14 September 2006 (UTC)

To be honest I don't know. I created the page since the article for the Lead cooled fast reactor mentioned the possible use of LBE as a coolant, but didn't explain what it was and it's (dis)advantages as compared to lead. I pretty much used the article on NaK as a template. Maybe a hyphen would be more accurate. Maybe I will have a look at what the Generation IV initiative uses in it's roadmap. ( Btw, how do you rename pages ? ). 137.205.192.27 02:25, 18 September 2006 (UTC)

Just use the "move" tab at the top of the page. You might also want to make one Wikipedia:Redirect to the other. Thanks, William Pietri 03:46, 18 September 2006 (UTC)

The redirect is auto-created when moving. However, one can't move pages without a login with 25+ edits (one of the reasons to register). I'll do it now myself. CP/M ^comm |Wikipedia Neutrality Project| 11:06, 18 September 2006 (UTC)

Advantage?

The advantage of LBE over unradioactive lead is the lower melting point?

Yes. The lower melting point makes it somewhat easier to restart a reactor that has been shut down, makes it easier to refuel it and also means you can perform ultrasonic inspection of reactor components at lower temperatures making the fabrication of devices to do so easier. However the increased radioativity of the coolant have the opposite effect. Also, I seem to remember that Bismuth is more corrosive than lead, but don't quote me on that. 213.55.27.154 04:15, 21 March 2007 (UTC)

Of course. Why else would you choose an extra-low-melting alloy if there wasn't any advantage to that? It's the boiling point, as the article says, which should be as high as possible. --BjKa (talk) 14:39, 15 November 2017 (UTC)

Basic properties

The article currently doesn't mention either the percentage of lead and bismuth, or the melting and boiling points of the eutectic. --JWB 06:36, 14 May 2007 (UTC)

History

Allegedly, this was used historically for typesetting purposes (ie: not just a nuclear coolant).

Page 150 of the March 9th, 1889 issue of Scientific American magazine mentions the use of bismuth in typesetting alloys to soften the metal. This was however in a proportion of 9 parts lead to 2 parts antimony and 2 parts bismuth, not the alloy described in this Wikipedia page.
