Transparent Aluminum is Here
Slashdot ^ | 8/23/2004 | Hemos

Posted on 08/23/2004 7:16:42 AM PDT by sionnsar

from the like-blue-LEDs dept. Alien54 writes "Scientists in the US have developed a novel technique to make bulk quantities of glass from alumina for the first time. (link includes a picture of samples)

Anatoly Rosenflanz and colleagues at 3M in Minnesota used a "flame-spray" technique to alloy alumina (aluminium oxide) with rare-earth metal oxides to produce strong glass with good optical properties. The method avoids many of the problems encountered in conventional glass forming and could, say the team, be extended to other oxides (see also: A Rosenflanz et al. 2004 Nature 430 761).

Scotty would be pleased."

The title is goofy. Aluminum is a metal. Aluminum oxide is already transparent and exists in crystaline and amorphous states. There is also no alloy here, the compound Al2O3 has simply been mixed with other compounds to effect structure. The goal is toughness. That's all.

Luckily my brain has plenty of room for trivial items. :^)

Did you know John Ratzenberger (Of "Cheers") appeared in THE EMPIRE STRIKES BACK?

Perhaps it was here before but nobody was able to see it.

I always wondered how Scotty produced all those cool animated graphics so quickly on an ancient (to him) Macintosh. I also wondered if I could navigate an ancient Timex Sinclair or Altair (old operating systems) so quickly and efficiently. Scotty was truly a "miracle worker".

This stuff has been around for quite a while. You will often see it used in halogen light bulbs.

I agree. I would leave this mudball full of idiots in a heartbeat. The U.S. became the the scientific powerhouse because other countries made life too difficult for people and the smart ones left. If there was a planet available for settling by humans, the same thing would happen.

First flip phones, now aluminium, soon warp drive, I hope.

I showed my kids "The Trouble With Tribbles" the other day. When Kirk pulled out his communicator they laughted. I asked them what was funny and they said, "Look how BIG it is."

Hopefully Warp Drive will also be that much better than what ST predicted. Shalom.

Hello, computer?

Just use the keyboard.

Keyboard? How quaint!

Yah, he was the guy who said "A little known fact about the Ewoks is that they actually have 7 kidneys..."

No transparent aluminum.

Aluminum is a metal, alumina is an oxide (compound) of aluminum, and quite a different beast -- just as hydrogen is very different from water (hydrogen oxide).

The link doesn't work for me.

Hm. Which one? It could be the dreaded Slashdot effect -- an overloaded server.

Also, the word "ewok" is never uttered in the JEDI film.
