Manganese

Manganese wani sinadari ne mai alamar Mn, lambar atomic lamba 25, da kuma dangin atomic mass 54.9380, fari ne mai launin toka, mai wuya, gagajewa, da ƙarfe mai sheki. Matsakaicin dangi shine 7.21g/cm³ (a, 20℃). Farashin 1244℃, tafasar batu 2095℃. Resistivity shine 185 × 10Ω·m (25℃).

Manganese farin ƙarfe ne mai ƙarfi da karɓaɓɓe tare da tsarin lu'ulu'u ko tetragonal crystal. Girman dangi shine 7.21g/cm ³ (a, 20 ℃). Matsayin narkewa 1244 ℃, wurin tafasa 2095 ℃. Resistivity shine 185 × 10 Ω · m (25 ℃). Manganese wani ƙarfe ne mai amsawa wanda ke ƙonewa a cikin iskar oxygen, oxidizes akan samansa a cikin iska, kuma yana iya haɗuwa kai tsaye tare da halogens don samar da halides.

Manganese ba ya wanzu a matsayin nau'i ɗaya a cikin yanayi, amma manganese tama yana da yawa a cikin nau'i na oxides, silicates, da carbonates. Manganese tama ana rarrabawa a Australia, Brazil, Gabon, Indiya, Rasha, da Afirka ta Kudu. Nodules na manganese a kan bene na duniya sun ƙunshi kusan 24% manganese. Ma'adinan albarkatun manganese a Afirka ya kai ton biliyan 14, wanda ya kai kashi 67% na arzikin duniya. Kasar Sin tana da albarkatun manganese mai yawa, wadanda ake rarrabawa da samar da su a larduna 21 na kasar..
