Never heard of it until I stumbled upon an article about it today. Interesting stuff. Here is a page about it:

GCT said:Yep "hydrides" right?
gravenewworld said:Nope. It is when hydrogen is placed under an immense amount of pressure (something like 5 million atmpospheres), you get a different allotrope of hydrogen that behaves more like a metal (like being able to conduct electricity).
Hydrogen is above the rest of the alkali metals, so why can't it behave like the rest of them?
It sounds like really neat stuff.
interesting how it turns into liquid metal
wonder how it looks...
This is not the reason that hydrogen "can" be metallized. In theory, any non-metal will lose its band gap at some sufficiently high pressure, and become a conductor.gravenewworld said:Hydrogen is above the rest of the alkali metals, so why can't it behave like the rest of them?
Do you have a reference?grandunifier said:They've found a novel way to Metallic hydrogen, in prestressed lattices of SiH4, something to do with a novel LASER approach to making it.
much easier than gas guns.

Metallic hydrogen is a phase of hydrogen in which the gas transforms into a solid metal-like form under extreme pressure and cold temperatures. It is considered a rare substance because it only exists in certain conditions that are difficult to reproduce in a laboratory.
Metallic hydrogen is typically produced by compressing hydrogen gas to pressures above 20 GPa (gigapascals) while simultaneously cooling it to temperatures below 100 K (kelvins). This can be achieved using a diamond anvil cell or a shock tube apparatus.
Metallic hydrogen has unique properties, including high electrical and thermal conductivity, high reflectivity, and superconductivity at low temperatures. It is also predicted to be a room-temperature superconductor, meaning it can conduct electricity with zero resistance at room temperature.
The potential applications of metallic hydrogen are still being researched and explored. Some possible applications include its use as a clean energy source due to its high energy density, as well as its potential use in high-performance electronics and superconductors.
No, metallic hydrogen is not naturally found on Earth. It is only created in laboratory settings using specialized equipment. However, it is believed that metallic hydrogen may exist in the cores of gas giant planets, such as Jupiter and Saturn, due to their immense pressure and cold temperatures.
