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."

He did say "a keyboard, how . . "

Kirk handed Scotty the mouse and he spoke into it, then someone pointed out the keyboard.

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

The headline is misleading. Alumina is an oxide of aluminum not a metal. Where do journalists get their science training, public school?

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.

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".

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.

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.

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).

They did. They traded the knowledge of transparent aluminum for the plexiglass for the whale tank. This is evidenced by the owner/manager/foreman of the plant saying "It would take years to work out this matrix".

Excuse me but this is not a NEW process! Indeed, the first production of "transparant" alumina occured in 1902!! Its called a Ruby

The year 1902 saw the first production of synthetic ruby using the Verneuil flame-fusion process. Later, sapphire, spinel, rutile, and strontium titanate were grown with this technique. In this process, a single crystal, called a boule, forms in the flame of a simple, downward-impinging oxygen-hydrogen blowtorch. Pure oxides of aluminum (in the cases of ruby, sapphire, and spinel) or titanium (rutile and strontium titanate) are poured into the top of a small furnace and melted. Other oxides are added as needed for process control and to obtain the specific color desired. The melted material solidifies as a boule on a rotating fire-clay peg as the peg is slowly withdrawn. A boule has a very characteristic shape, with a rounded end, a long cylindrical body, and a tapering end. It is usually about 13 to 25 millimeters in diameter, 50 to 100 millimeters long, and weighs 75 to 250 carats.

Another melt technique is the Bridgman-Stockbarge solidification method, named for an American, P.W. Bridgman, and a German, D.C. Stockbarge, who, aided by three Russians, J. Obreimov, G. Tammann, and L. Shubnikov, discovered and perfected the process between 1924 and 1936. Currently, the method is used primarily for growing nongem halide, sulfide, and various metallic oxide crystals, one of the metallic oxides being aluminum oxide or sapphire

Lead glass was the rage until about 1902when it was removed from the formula for meaking glass. Today some older pieces of collectible glass are tinted the lightest blue or pink due to exposure to the sun. This so called "sun colored glass" is one way to guess the age of a particular glass. I was at a farm auction in North Dakota and there was a wreck of a vehicle that appeared to be an early Ford. Its headlights were pink and I tried to buy them but the whole auto carcass was bought by an auto fixer upper!
