Manganese

Manganese waa curiye kiimiko ah oo leh summada Mn, lambarka atomiiga 25, iyo cufnaanta atomiiga 54.9380, waa caddaan cawl, adag, jajaban, iyo dhalaalaysa bir kala guurka ah. Cufnaanta qaraabo waa 7.21g/cm³ (a, 20℃). Meeting point 1244℃, barta karkarinta 2095℃. resistivity waa 185×10Ω·m (25℃).

Manganese waa bir cad oo qalin ah oo adag oo jajaban oo leh nidaam kubik ama tetragonal crystal ah. Cufnaanta qaraabo waa 7.21g/cm ³ (a, 20 ℃). Barta dhalaalka 1244 ℃, barta karkarinta 2095 ℃. Iska caabintu waa 185×10 Ω·m (25 ℃). Manganese waa bir fal-celisa oo ku gubta ogsijiinta, oksidhis ku samaysa dusheeda hawada, waxayna si toos ah isugu dari kartaa halogens si ay u sameeyaan halides.

Manganese ma jiraan hal walxood oo dabiiciga ah, laakiin macdanta manganese waxay ku badan tahay qaabka oxides, silicates, iyo carbonates. Macdanta Manganese waxaa inta badan lagu qaybiyaa Australia, Brazil, Gabon, India, Russia, iyo South Africa. Noodles manganese ee ku yaal sagxadda badda ee dhulka ayaa ka kooban qiyaastii 24% manganese. Kaydka macdanta manganese ee Afrika waa 14 bilyan oo tan, taas oo ka dhigan 67% kaydka caalamiga ah. Shiinaha waxa uu leeyahay khayraad badan oo manganese ah, kaas oo si weyn loo qaybiyo lagana soo saaro 21 gobol (gobolada) ee dalka oo dhan..
