IManganese

IManganese iyikhemikhali enophawu Mn, inombolo ye-athomu engu-25, kanye nesisindo se-athomu esihlobene 54.9380, iyinsimbi empunga emhlophe, eqinile, eshwabene, necwebezelayo. Ukuminyana okuhlobene kungu-7.21g/cm³ (a, 20). Iphuzu elincibilikayo 1244, iphoyinti elibilisa ngo-2095. I-resistant yi-185 × 10Ω·m (25).

IManganese iyinsimbi emhlophe eqinile futhi ephukayo ene-cubic noma i-tetragonal crystal system. Ukuminyana okuhlobene kungu-7.21g/cm ³ (a, 20 ℃). Iphuzu elincibilikayo 1244 ℃, iphoyinti abilayo 2095 ℃. I-resistivity ingu-185×10 Ω· m (25 ℃). I-Manganese iyinsimbi esebenzayo eshisa umoya-mpilo, i-oxidize ebusweni bayo emoyeni, futhi ingahlangana ngokuqondile nama-halogen ukuze yakhe i-halides.

I-Manganese ayikho njengento eyodwa emvelweni, kodwa i-manganese ore ivamile ngendlela yama-oxides, ama-silicates, nama-carbonates. I-Manganese ore isatshalaliswa kakhulu e-Australia, Brazil, Gabon, India, Russia, naseNingizimu Afrika. Amaqhuqhuva e-manganese angaphansi komhlaba aqukethe cishe u-24% we-manganese. Izinqolobane zemithombo ye-manganese ore e-Afrika zingamathani ayizigidi eziyizinkulungwane eziyi-14, okwenza u-67% wemithombo yomhlaba wonke..
