ammonia reactivity

[Nick1911]

Weird question: what metals are generally non-reactive with ammonia?

Near as I can figure, stainless steel is about it.

Gold

Mild steel as well...

titanium

Isn't gold non reactive with pretty much everything?

Yep.

H1? when there's no budget, i know just what you need.

Plastic.

Yes, it's a metal.  The chemists have their conspiracies too.

How can plastic be a metal when it's mostly hydrocarbons, and neither hydrogen or carbon are metals...?

Have you verified this yourself, using equipment that you built from scratch?

Conspiracies among scientists run deep, and they have years of schooling in how to maintain the illusions.

What you do, see, is take something that's long chains of non-metallic hydrogen and carbon atoms and say that it's something consisting of metallic atoms.  Why?  Well... because you can.

Having trouble sleeping?  Ask a chemist how shampoo works.

Most ammonia systems I see in plants are either carbon steel or stainless steel.  Avoid copper alloys.

Get a kitten.

Wait one year.

Whatever isn't ruined is "Ammonia Resistant".

Hydrogen can be a metal . . .

Metallic hydrogen is a sort of super-compressed hydrogen found in the cores of gas giants and stars. As hydrogen tops the Periodic Table's alkali metal column, it has been known for a while it has the potential to be a metal, but only under extreme pressures. Metallic hydrogen is crushed so closely that the atomic nuclei are separated only by a dense electron soup which flows between them. It is significantly less dense than neutronium, however, where the electrons merge together with the protons in hydrogen to make neutrons. Like all metals, metallic hydrogen is conductive and requires an electrical current to measure the presence of metallization.

Metallic hydrogen was only synthesized under laboratory conditions as recently as 1996, at the Lawrence Livermore National Laboratory. It only existed for about a microsecond, and required temperatures of thousands of degrees and pressure over a million atmospheres to achieve. This was a surprise, as it was previously thought that solid (very cold) hydrogen was required to produce metallic hydrogen. Previous experiments subjected solid hydrogen to pressures up to 2.5 million atmospheres, with the absence of any detectable metallization, so the experiment involving the compression of hot hydrogen was set up to measure other properties of the material, not with the intention of producing metallic hydrogen. Nevertheless, that's how metallic hydrogen was first made.

Although the metallic hydrogen produced at the Lawrence Livermore National Laboratory was solid, it has been theorized that it may be possible to create liquid metallic hydrogen, if even greater pressures, around 4 million atmospheres, are used. Calculations have also determined that metallic hydrogen might be a superconductor at room temperature, although this property would be somewhat useless for practical purposes, as the cost of compressing something to over a million atmospheres for an extended period of time is much greater than cooling something down to near absolute zero. However, there is a small chance that metastable metallic hydrogen might be possible -- that is, metallic hydrogen which retains its phase even when the pressure is removed.

It is thought that metallic hydrogen exists in the cores of the larger gas giants in our solar system: Jupiter and Saturn, as well as a hydrogen shell near the core of the Sun.

Don't store your aqua regia in a gold bottle . . .

Mmmm, electron soup! 

[AJ Dual]

I wonder what meta-stable Metallic Hydrogen would be like? Just how stable is meta-stable?

Would it be soft, like metallic Sodium?  

With such a high proton density, it would make an excellent light-weight radiation shield for spacecraft.  It would probably also make a great fuel, very compact.

[280plus]

Plus there's soup!

Like plastic.  That whole "extreme pressure and temperature" thing was just another part of the coverup; somebody outside the conspiracy got too close to seeing through their ruse, and they had to come up with something to explain away his research.

They get really in-depth with these things; look at all they're doing to fake the whole "oil spill" in the Gulf of Mexico just to cover up the dumping from Al Gore's last fleet oil change.

Remember, the Catholic Church is in on it. So when the SHTF if you really want to survive head for the nearest Catholic church and you'll be safe. They're all prepared, they have bunkers and everything. It's true, Bill the painter told me so. He thought I would think he was just a nut cause he was just a lowly painter but he was wrong, I believed every word he said.

I thought if you just froze hydrogen it turned out to be metallic.  (−259.14 °C)

And if you freeze dihydrogen monoxide it turns out to be really slick.

Problem is, it's more of a pollutant than carbon dioxide - I mean, the very water we drink, even if purified and filtered, still has it in very high concentration.

I hear it's been found to be present in over 95% of cancerous tumors, too, but there's no carcinogen warning for it.
