Oxide - Wikipedia

An oxide / ˈ ɒ k s aɪ d / is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O 2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

Thermite | Project Gutenberg Self-Publishing - eBooks ...

Red iron(III) oxide (Fe 2 O 3, commonly known as rust) is the most common iron oxide used in thermite. Magnetite also works. Other oxides are occasionally used, such as MnO 2 in manganese thermite, Cr 2 O 3 in chromium thermite, quartz in silicon thermite, or copper(II) oxide in copper thermite, but only for specialized purposes.

The reduction and oxidation behaviour of manganese oxides ...

The reduction of manganese oxides with methane was studied to investigate the suitability of manganese as an oxygen storage compound. Manganese oxides are reduced by CH 4 to a lower-valent manganese oxide, producing CO 2 and water. Once the manganese oxide is reduced, it can be regenerated, i.e. reoxidised.
