:Oxyde de manganèse (MnO2)
Description :
Oxyde de manganèse (MnO2) est un solide noir ou brun qui se trouve naturellement sous forme de minéral pyrolusite, qui est le principal minerai de manganèse. C'est un composé inorganique caractérisé par son état d'oxydation élevé du manganèse, où le manganèse est à l'état d'oxydation +4. MnO2 est insoluble dans l'eau mais peut se dissoudre dans les acides, formant des sels de manganèse. Ce composé présente des propriétés paramagnétiques en raison de la présence d'électrons non appariés dans ses orbitales d. Il est couramment utilisé comme catalyseur dans diverses réactions chimiques, y compris la décomposition du peroxyde d'hydrogène, et comme pigment dans les céramiques et le verre. De plus, le MnO2 joue un rôle significatif dans les batteries, en particulier dans les batteries alcalines, où il agit comme dépolariseur. La substance est également utilisée dans la production d'autres composés de manganèse et dans les processus de traitement des eaux usées. Les considérations de sécurité incluent son potentiel à provoquer une irritation respiratoire par inhalation et une irritation cutanée par contact, nécessitant des mesures de manipulation appropriées.

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>Formule :MnO2Degré de pureté :Min. 95%Masse moléculaire :86.94 g/mol
