Óxido de manganeso (MnO2)

Descripción:
Óxido de manganeso (MnO2) es un sólido negro o marrón que ocurre naturalmente como el mineral pirolusita, que es el mineral principal de manganeso. Es un compuesto inorgánico caracterizado por su alto estado de oxidación de manganeso, donde el manganeso está en el estado de oxidación +4. MnO2 es insoluble en agua pero puede disolverse en ácidos, formando sales de manganeso. Este compuesto exhibe propiedades paramagnéticas debido a la presencia de electrones desapareados en sus orbitales d. Se utiliza comúnmente como catalizador en varias reacciones químicas, incluida la descomposición del peróxido de hidrógeno, y como pigmento en cerámicas y vidrio. Además, MnO2 juega un papel significativo en las baterías, particularmente en las baterías alcalinas, donde actúa como despolarizador. La sustancia también se utiliza en la producción de otros compuestos de manganeso y en procesos de tratamiento de aguas residuales. Las consideraciones de seguridad incluyen su potencial para causar irritación respiratoria al inhalarse y irritación en la piel al contacto, lo que requiere medidas de manejo adecuadas.

  • Manganese (IV) oxide - min90%

    CAS:
    <p>Manganese (IV) oxide is a reactive metal that is used in the production of sulfuric acid, fertilizers, and other chemicals. It has been found to have antioxidant effects and can be used for the treatment of oxidative injury. Manganese (IV) oxide has also been shown to have a protective effect on cells against radiation by inhibiting lipid peroxidation and protecting cell membranes from damage. Manganese (IV) oxide nanoparticles are used as a model system for studying brain function, due to their ability to penetrate the blood-brain barrier. Manganese oxides are also used in wastewater treatment, because they react with nitrogen compounds and produce ammonia gas which can be removed by a scrubber.</p>
