Solved: Manganese Metal Is Produced From The …
Manganese metal is produced from the manganese(III) oxide, Mn2O3, which is found in manganite, a manganese ore. The manganese is reduced from its +3 oxidation state in Mn2O3 to the zero oxidation state of the uncharged metal by reacting the Mn2O3 with a reducing agent such as aluminum or carbon.

Oxide Ceramics – Aluminum Oxide (Al2O3)
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. CeramTec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
Aluminum | Encyclopedia
Aluminum oxide, Al 2 O 3, often called alumina, does not melt until over 3, 632 F (2, 000 C), and is used to line furnaces. Other forms of alumina are corundum and emery, which are very hard and are used as abrasives. Among the many other mineral forms

How do I balance the chemical equation …
2010/7/19· Let''s look at cobalt (III) oxide. Cobalt (III) means its cobalt ion with valency of 3 and since metals form positive ions, this is Co3+ ion. Oxide ion = O2- Thus cobalt (III) oxide should have the chemical formula Co2O3 (swop the valencies to get the formula of the compound formed) Balanced chemical equation: 4Co + 3O2 --> 2Co2O3 Hope this helps.
