Manganese dioxide pauda nanoMnO2 nanopowder/nanoparticles

ʻO ka wehewehe huahana no ka pauka manganese dioxide MnO2:

ʻO Manganese(IV) dioxide MnO2 ka mea hoʻohuihui inorganic me ke ʻano MnO 2. ʻO kēia paʻa ʻeleʻele a ʻeleʻele paha e hana maoli ʻia e like me ka mineral pyrolusite, ʻo ia ka mea nui o ka manganese a me kahi ʻāpana o nā nodules manganese.ʻO ka hoʻohana nui ʻana no ka MnO 2 no nā ʻaʻa kelepona maloʻo, e like me ka pā alkaline a me ka pākahi zinc-carbon.Hoʻohana ʻia ʻo MnO 2 ma ke ʻano he puaʻa a ma ke ʻano he precursor i nā pūhui manganese ʻē aʻe, e like me KMnO 4. Hoʻohana ʻia ʻo ia ma ke ʻano he reagent i ka synthesis organik, no ka laʻana, no ka oxidation o allylic alcohols.Hiki i ka MnO 2 i loko o ka α polymorph ke hoʻokomo i nā ʻano ʻano like ʻole (me nā molekele wai) i loko o nā "tunnels" a i ʻole "kanela" ma waena o ka magnesium oxide octahedra.Nui ka hoihoi i ka α-MnO 2 ma ke ʻano he cathode hiki ke hoʻopaʻa ʻia no nā pākahi lithium ion.

Ka hoʻohana ʻana i ka pauka manganese dioxide MnO2:

 Hoʻohana nui ʻia ka manganese dioxide no ka ʻoihana lāʻau lapaʻau a hoʻohana pū ʻia i nā ʻoihana aniani uila, nā mea magnetic, dye, ceramic, colorbrik etc.
