Metals may seem tough, but given enough time even plain old air can be their undoing. Oxygen reacts with it to form metal oxides like rust, but now it turns out a metal oxide may come to the rescue.

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, forming ...

Bioleaching close bioleachingUsing bacteria to extract metals from their ores. is used to extract small quantities of metals from mining waste heaps. Electrolysis can be used to extract the metal from ...

Aluminium is derived from the mineral bauxite. Bauxite is converted to aluminium oxide (alumina) via the Bayer Process. The alumina is then converted to aluminium metal using electrolytic cells and ...

Alumina (Aluminium Oxide) is the most widely used oxide ceramic material. Its applications are widespread, and include spark plugs, tap washers, abrasion resistant tiles, and cutting tools. Very large ...
