- jmount 4y agoOr just saphire (Al2O3).
- hinkley 4y agoFancy watches still use sapphire “glass” displays right?
- jakzurr 4y agoSamsung Note-3 had tiny sapphire cover over main camera lens.
- musicale 4y agoI recall complaints (on youtube?) that Apple's sapphire glass formulation on the Apple watch can be scratched by pure sapphire, but presumably it trades off some scratch resistance for greater impact resistance, though it's probably still more brittle than regular gorilla glass.
- DoreenMichele 4y agoTechnically, the Wikipedia article is called Aluminium oxynitride. Please don't tell the mod. This title (Transparent Aluminum) is more informative and also works as a Star Trek reference, which isn't a bad thing.
- lostmsu 4y ago> This title is more informative No, it is not. It is no more "transparent aluminium" than glass is a "transparent silicon".

- jldugger 4y agoI mean, thats more or less correct, though. It just isn't like, what we make interstellar spaceship chassis out of. But we might put it in windows of the ISS.

- spauka 4y agoWorth noting that the material is not conductive or otherwise metallic in any way. In a lot of ways this material is similar to Alumina (Sapphire) which you could also describe as "Transparent Aluminum". Conductive transparent materials do exist (see ITO https://en.wikipedia.org/wiki/Indium_tin_oxide https://en.wikipedia.org/wiki/Indium_tin_oxide), but this is not it.
- 0_____0 4y agoNot sure I would qualify ITO as transparent. The thicker the coating the less transmission (but lower resistance) you get.
- A_D_E_P_T 4y agoIt's also highly brittle, with a fracture toughness of 2 MPa.m1/2 -- which makes it only marginally tougher than borosilicate glass, and broadly equivalent to many brittle ceramics such as silicon carbide. 6061 aluminum has a fracture toughness of roughly 29 MPa.m1/2. So "transparent aluminum" exhibits fracture behavior that is much more glass-like than aluminum-like.
- andrewflnr 4y agoYeah, I was kind of wondering what they need that nitrogen there for. Maybe ALON is easier to manufacture in bulk or something...
- elihu 4y agoHow do you cut it, I wonder? Tile cutting saw? Water jet? Can it be scored and broken in a straight line like glass?
- iancmceachern 4y agoYes. It's just like processing any other ceramic
- LeoPanthera 4y agoSince everyone is now thinking of Star Trek IV: The computer that Scotty uses in the Plexicorp scene appears to be a Macintosh Plus, but its internals were completely changed for filming. Its screen was replaced with one from an IBM PC to make it easier to synchronize its video refresh rate with the film camera's frame rate, and the "transparent aluminum" animation was created on an IBM PC by computer graphics company Video Image. At one hour and one minute into the film, when Dr. McCoy hands Scotty the computer's mouse, is one of the few times James Doohan's missing right middle finger is visible in the entire franchise. The finger was shot off during the invasion of Juno Beach on D-Day. The computer that Scotty uses to show transparent aluminum was originally going to be an Amiga, but Commodore would only give permission if they bought their own. Apple Computer was willing to give them a Mac for free.
- jksmith 4y ago>The computer that Scotty uses to show transparent aluminum was originally going to be an Amiga, but Commodore would only give permission if they bought their own. Apple Computer was willing to give them a Mac for free. Without knowing all the details, that seems like a dumb move by Commodore. Too bad though that some geeks weren't consulted, since they might have fixed up a Symbolics machine for the scene, which was a movie prop during the 80's.
- LocalH 4y agoSounds like typical Commodore handling of the Amiga. They bungled the shit out of it.
- bigmattystyles 4y agoI like this scene a lot but my favorite one is McCoy in the hospital, especially the scene in the elevator where he is horrified we’re still using chemotherapy.

- jbm 4y agoI wish there was an actual picture instead of just a molecular structure graph. I found one here: https://makezine.com/article/science/transparent-aluminum/ https://makezine.com/article/science/transparent-aluminum/ Also a video of it being used as Armor? https://www.youtube.com/watch?v=RnUszxx2pYc https://www.youtube.com/watch?v=RnUszxx2pYc
