The chemical name of manganese dioxide is MnO2. This mineral is a dark steel-gray, crystalline solid. It has a density of 5.08 grams per cubic centimeter.
Manganese dioxide is a common ingredient in batteries. It is used as a depolarizer in dry cell batteries. In addition, it is used as a reagent in organic synthesis. Other uses for the compound include printing, dyeing textiles, and pyrotechnics.
Generally, the use of manganese dioxide is accompanied by the use of ventilation to keep airborne concentrations below permissible exposure limits. However, some studies have shown that inhaling manganese dioxide can cause respiratory diseases. These can range from simple coughing to more serious pneumonia.
If you are exposed to the chemicals, wash contaminated clothing and skin, and try to induce vomiting. Once you have completed these steps, you can proceed to the medical facility to receive treatment.
While it is rare for manganese dioxide to be considered a human carcinogen, it is possible that it may be toxic to human development and reproductive systems. Because of this, it should be kept away from reducing agents.
The chemical is a component of dry cell batteries and is also used in fireworks. It is also an important precursor to ferromanganese, an alloy of iron.
