My friends says he once read an article (i'm not sure from where) that states there were some scientists that managed to turn water into alloy.
I guess they compressed the water to a ridiculous extent and then shot x-rays at it all day.
Have you guys heard of this? Do you know how this happens?
The molecules must've restructured right? If so, if the alloy was heated to a liquid state would it be water again?
This is actually probably a chemistry question. I'm not really sure i've never taken chemistry or physics...

An alloy?
Alloy, as far as I know, refers to a mixture of metals into a new substance. Water is not a metal, and while you could mix things into water, we usually call that a solution, or perhaps just dirty water.
It has nothing to do with molecular restructuring; alloying revolves around structures larger than molecules.
Given what you mentioned here, the water was apparently turned into some sort of solid that is fundamentally different from ice? The only thing I could think of was that someone made a solid version of hydrogen peroxide, but not only would that be a terrible idea, it wouldn't be water.
So how could this be different from dirty ice?

There are actually several different types of ice with different crystalline structures. At very high pressures water freezes at very high temperatures. Like Layra-chan said, water cannot be by definition an alloy because the word alloy refers to more than one mix of metals. I suppose you can mix water with metals (which is why water is conductive) and then apply a high pressure to it until it turns into a solid at relatively normal temperatures. Unless you can use it in an environment which is naturally at a high pressure, there's not much you can do with a mixture of ice and metal.

Perhaps they meant some sort of hydrated crystal (such as Copper(II) Sulfate pentahydrate) that does not decompose at melting point, which I doubt exists because when a hydrated crystal reaches its "melting point" the water is free to move and evaporate. Could you ask your friend where he found this article so we may all have a glance?

Haha i didn't know an alloy was a mixture of metals XD But you guys all seemed to know that... lol anyways, i found the article here on new scientist: Ice, Steam, Liquid, and now a new type of metalIt says something about the x-rays breaking down the atoms in the molecule and the... atoms restructuring and somehow that forms an alloy. but you are all definitely right i looked it up, alloys are mixtures of metals... XD

Well, they're completely misusing the term "alloy," where the word they want is probably compound. What they want is probably a mixture, depending on the exact configuration of the hydrogen and oxygen molecules. From the article, I gather that it's a mixture of O2 and H2 that is stable at high pressures. If anything, it's an alloy of oxygen and hydrogen, although that's still misusing the word alloy.
This is quite interesting, though, if it doesn't react back to water spontaneously.

they said the alloy could withstand high heats and retain it's form as a compound...alloy...metal thing.
but if it was heated would it just be h2o2 in liquid form?
i wonder why i haven't seen/heard of this being used, the article is kind of old.

For some reason it reminds me of the polywater experiments in the 1960's.
