Sapphire is a high-purity and high-density, single-crystalline form of aluminum oxide that may contain chromia, titania, yttria, or other dopants. Sapphire is usually transparent or translucent.

Zirconium-aluminium system is a multiple phase binary system, exhibiting low solid solubility at either ends of a phase diagram. The present note reports certain features of layer growth in ...

In the lab Researchers at TU Wien employed noncontact atomic force microscopy and computational modelling to determine the structure of the aluminium oxide surface. (Courtesy: TU Wien) Determining the ...

Sodium aluminate forms through the chemical reaction of aluminum oxide with sodium hydroxide and water, as follows: The residues sink gradually to the bottom of the tank and are later removed. In the ...

It looks like a tube made of glass but it’s actually aluminum. Well, aluminum with an asterisk beside it — this is not elemental aluminum but rather a material made using it. We got onto the ...

Zirconium is a metal in group IVB of the periodic table with atomic number 40, an atomic weight of 91.22, and a density of 6.49 Mg/m 3. Its melting point is 1852 C, and it boils at 3580 C. The ...

When comparing antiperspirants to some of the best aluminum-free deodorants, experts say there’s one clear difference. Though studies indicate there’s no direct link between aluminum-based ...

With so much else happening in the news, aluminum buyers could easily overlook the recent Guinea export ban on bauxite to Emirates Global Aluminum. Since smelters need two tons of alumina for ...

Aluminum zirconium, zinc, and thorium are common mix-ins. They allow the alloy to be precipitation hardened — a heat treating process that forms microscopic regions called precipitates that ...

Aluminum is a metal in group IIIA of the periodic table with atomic number 13, an atomic weight of 26.982, and a density of 2.70. It has a melting temperature of 660 C. The electronic configuration of ...
