TRANSPARENT ALUMINUM - CLEAR METAL?!
Youtube ^ | 7-24-2017 | Tiffany Loverd

Posted on 02/21/2018 8:01:36 PM PST by goldendelicious

Aluminium oxynitride or AlON is a ceramic composed of aluminium, oxygen and nitrogen. It is marketed under the name ALON by Surmet Corporation. AlON is optically transparent (≥80%) in the near-ultraviolet, visible and midwave-infrared regions of the electromagnetic spectrum. It is 4 times harder than fused silica glass, 85% as hard as sapphire, and nearly 15% harder than magnesium aluminate spinel. Since it has a cubic spinel structure, it can be fabricated to transparent windows, plates, domes, rods, tubes and other forms using conventional ceramic powder processing techniques. ALON is the hardest polycrystalline transparent ceramic available commercially. Combination of optical and mechanical properties makes this material a leading candidate for lightweight high-performance transparent armor applications such as bulletproof and blast-resistant windows and for many military infrared optics. AlON-based armor has been shown to stop multiple armor-piercing projectiles of up to 50 cal. It is commercially available in sizes as big as 18x35-inch monolithic windows.

ALON can be fabricated as windows, plates, domes, rods, tubes and other forms using conventional ceramic powder processing techniques. Its composition can vary slightly: the aluminium content from about 30% to 36%, which has been reported to affect the bulk and shear moduli by only 1–2%.) The fabricated greenware is subjected to heat treatment (densification) at elevated temperatures followed by grinding and polishing to transparency. It can withstand temperatures of about 2100 °C in inert atmospheres. The grinding and polishing substantially improves the impact resistance and other mechanical properties of armor.

Yes, I remember when Steve Jobs invented it ;-)

I’m pretty sure it was stolen from Wakanda

Well that certainly changes everything. I’m on board now.

I wonder if they can use this stuff in spacecraft windows.

The Wakandans neglected to patent it.

Can it be used to make the domes for Mars colonies?

It can but unfortunately the Xhosa clicking will crack it.

Aluminum oxide aka sapphire is transparent. A transparent compound with a metallic cation does not constitute a ‘transparent metal’.

I wonder when it will be available for cars and motorcycle windshields. Soon I hope and at a price that doesn’t break the bank.

Yes, but this is still pretty cool
