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.

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 ...

Aluminum naturally forms an oxide layer on its surface when exposed to air. Anodizing in an electrolytic cell creates a thicker oxide layer that makes the part more resistant to corrosion and wear.

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 ...

However, the aluminium used in the construction, when burning in the atmosphere, forms aluminium oxide, which remains in the ...

To reduce costs, powdered aluminium oxide is dissolved in molten cryolite. This ionic compound melts at a lower temperature than aluminium oxide. The oxygen reacts with the carbon anodes ...

Aluminium is more reactive than carbon so it must be extracted from its compounds using electrolysis. Even though aluminium is more abundant than iron in the Earth's crust, aluminium is more ...
