Hello! How can I assist you today?
Some things they did get right...
Misleading name, on the same level as calling water "non-explosive hydrogen". That said the material looks promising, as a glass replacement for some applications (the text mentions a few of them, like armoured windows).
(It is not a metal; it's a ceramic, mostly oxygen with bits and bobs of aluminium and nitrogen. Interesting nonetheless, even if I'm picking on the name.)
The obtained material, which is molded and opaque, is heated to 2000 C and kept at this temperature for two days
Fuck that's a long time and a high temp
I had no idea this actually existed! Cool!
Here’s a more novice-friendly link: https://hackaday.com/2018/04/03/whats-the-deal-with-transparent-aluminum/
Star trek comes to life, yet again.
This one goes the other way. It was first patented in the 80s before the movie came out. It just wasn't a big thing yet. I assume it's had improved properties since then, but the process already existed.
The StarTrek episode with the transparent Aluminium was from 1986, transparent Aluminium was invented in 1985, but at this time they don't have the tecnologic measures to produce significant ammounts. Even today it's relative expensive to produce, ~$15 per Square inch.
Transparent aluminum is so weird, a piece of it was once passed around our office. It felt heavier and colder than I expected, which I guess is probably because it's much denser than most types of glass (I think it's only comparable to optical glass so it would be close to holding a high quality glass lens) and it looks like the thermal conductivity is way higher.
No, Glass has an amorph atomic structure, its tecnically an ultra dense liquid, metal always has a cristaline structure, way different, even in it's transparent form, Saphires and Rubies are also tecnically transparent Aluminium.
What do you mean no? Everything I said is true - I'm just describing my firsthand impression. Nowhere did I say transparent aluminum is a type of glass? I was just describing why it feels heavier and colder than you would expect since it looks like glass, of which most are less dense and less thermally conductive compared to transparent aluminum, which is not glass but makes sense to compare to in order to convey what handling a piece feels like.
FWIW, this has been around for about twenty years.
Yeah of course, they learned it in the eighties to be able to rescue some whales I think..
Since 1985, one year before this StarTrek episode. But until now not producible in bigger scale.
Looks like a cool new project for NileRed
I wonder if anyone will ever tell him about the “rose gold” trend that he kept calling purple gold. He really put a lot of effort in that one and it makes him seem isolated, in that there was no point in the creation of the video where the search for ‘purple gold’ could be revised to ‘rose gold’ and garner less clickbait attention like patents that have been circumvented.
Edit: I would’ve suggested blue gold to clarify the intermetallic nature over being strictly an alloy.
Except it's not clickbait - I'll cite Wikipedia so you can look yourself, but they're not the same thing.
Rose Gold is a proper alloy of Gold, made with Copper.
Purple Gold is an "intermetalic" (which have a different molecular structure to normal alloys and thus are more brittle), and is made with Aluminium.
Due to it's brittleness even amongst intermetalics, it is considered hard to work with, much more so than a proper alloy like Rose Gold. The only similarity they share is their colour ranges can overlap dependent on how they're made.
My first thought as well
Scotty would be proud.
Aluminum oxynitride is transparent aluminum, but alpha aluminum oxide, which is also transparent, is called Corundum, Ruby, or Sapphire. That name is dumb.
wait until they hear about transparent silicon
I dunno, sounds kinda dangerous.
Transparisteel is real? Neat!
Now make a plane please
Is this bullshit? Is it April first or something? I actually checked, no kidding!
Scotty is going to be such a badass. I'm glad we have him to look forward to.
It isn¡t but not so strange, even in Nature exist Transparent Aluminium, called Saphires and Rubies. It's called transparent Metal, because of it's atomic structure cristaline, not amorph like normal cristal of an Window. Metal, also Aluminium has a cristaline structure.
Did we lose some whales recently?
Used as an insulator? Are you sure?
Same as ceramic, even used in high Voltage
Sounds expensive.
