Cas 1313-13-9 Manganese dioxide ufa nano MnO2 nanopowder / nanoparticles

Manganese (IV) dioksidi MnO2 ndi chigawo cha inorganic ndi formula MnO 2. Cholimba chakuda kapena chofiirira chimapezeka mwachibadwa ngati mchere wa pyrolusite, womwe ndi chitsulo chachikulu cha manganese ndi chigawo cha manganese nodules. Ntchito yayikulu ya MnO 2 ndi mabatire owuma, monga batire ya alkaline ndi batire ya zinc-carbon. MnO 2 imagwiritsidwanso ntchito ngati pigment komanso ngati kalambulabwalo wa mankhwala ena a manganese, monga KMnO 4. Amagwiritsidwa ntchito ngati reagent mu organic synthesis, mwachitsanzo, chifukwa cha okosijeni wa allylic alcohols. MnO 2 mu α polymorph imatha kuphatikizira ma atomu osiyanasiyana (komanso mamolekyu amadzi) mu "ngalande" kapena ngalande" pakati pa octahedra ya magnesium oxide.
