Manganese(IV) oxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally
as the mineral pyrolusite, which is the main ore of manganese and a component of manganese
nodules. The
principal use for MnO2 is for
dry-cell batteries, such as the alkaline
battery and the zinc-carbon battery.
Detailed description
MnO2 is also used as
a pigment and as a precursor to other manganese compounds, such as KMnO4. It is used as a reagent in organic
synthesis, for
example, for the oxidation of allylicalcohols. MnO2 in the α polymorph can incorporate a
variety of atoms (as well as water molecules) in the "tunnels" or
"channels" between the magnesium oxide octahedra. There is
considerable interest in α-MnO2 as a
possible cathode for lithium ion batteries.
Applications
The predominant
application of MnO2 is as a component of dry cell batteries, so called Leclanché cell, or zinc–carbon batteries. Approximately 500,000 tonnes are consumed for this application
annually.[7] Other industrial
applications include the use of MnO2 as an inorganic pigment in ceramics and in glassmaking.
