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.

Aluminum oxide occurs naturally in the form of the mineral corundum, but the mineral is not used as a commercial abrasive except as a component of emery. Alumina-Zirconia (e.g., Norzon®) ...

Like their gemstone cousin the sapphire, rubies are just a variety of corundum, or aluminum oxide. Where sapphire gets its blue tint mainly from iron, rubies get their pink to blood-red hue from ...

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 ...

They found that by interspersing atomically thin layers of aluminum oxide after every few layers of HfO 2-ZrO 2, they could ...

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 ...

An international team of scientists have combined cyclic-olefin copolymers with a powder of aluminum oxide to create a ...

Aluminum doesn’t solder well, and that’s because of the oxide layer that rapidly forms on the surface. [Ted]’s solution is to scour the aluminum with some mineral oil. The goal is to scrape ...
