What did the Japanese need Mercury for exactly?--Moonlight Mile 22:48, 20 December 2006 (UTC)

What is "weapons-grade mercury"? I suspect that it should simply be called "mercury".

A quick google search doesn't mention it, but does mention mercury's use in uranium enrichment and fuses Alastairward 21:13, 5 January 2007 (UTC)

I have removed the phrase. Describing the mercury as "weapons-grade" implies that there was something special about it that differentiated it from "non-military" mercury. It was used in dozens of applications including mercury arc rectifiers, pharmaceuticals and anti-fouling paint for ships' bottoms (which relied upon mercury oxide at that time) as well as mercury fulminate for detonators. All of these things are needed in wartime as well as peacetime. "Weapons-grade mercury" is as meaningful as "weapons-grade rubber" or "weapons-grade sulphur". Jll 16:24, 15 January 2007 (UTC)
