Molybdenum, birtan qalinka ah-sida cawlan, inta badan laguma arko nolol maalmeedkeena, laakiin waxa ay inagu xeeran qaabab kala duwan. Haddi ay ahaan lahayd alloys-ka, siliga molybdenum-ka ee goynta siliga, ama tijaabada bartilmaameedka molybdenum, molybdenum si aamusnaan ah ayay u ciyaartaa doorkeeda. Dhawaaqa dhawaan ka soo baxay Wasaaradda Ganacsiga iyo Maamulka Guud ee Kastamka Koontaroolada Dhoofinta Qaar ka mid ah Badeecadaha Molybdenum-ka ayaa hoosta ka xariiqaya Muhiimada ay leedahay Molybdenum-ka.
Qaabkeeda saafiga ah, molybdenum waa bir qalin ah - bir cawl ah oo leh Mohs engegan 5.5. Barta dhalaalkeedu waa 2623 digrii oo la yaabka leh iyo karkarinta waa 4639 digrii, labaduba waxay si gaar ah ugu sarreeyaan walxaha dabiiciga ah. Kaliya tantalum, osmium, rhenium, tungsten, iyo kaarboon ayaa leh dhibco dhalaalid sare leh. oksaydhka Molybdenum wuxuu ka bilaabmaa 300 darajo, kaas oo si gaar ah ugu hooseeya biraha ganacsiga. Intaa waxaa dheer, molybdenum waxay leedahay iskudarka ugu hooseeya ee ballaadhinta kulaylka, taas oo ka dhigaysa doorasho aad u wanaagsan codsiyo badan oo heerkul sare ah-.
Molybdenum kuma jiraan qaabkeeda macdan saafiga ah ee Dhulka, laakiin waxay u dhacdaa sida oksaydhyada kala duwan ee macdanta. Qaabka aasaasiga ah, molybdenum waa bir qalin ah{1}} oo leh midabka birta cawlan. Waxay leedahay barta lixaad- ugu sareysa ee dhammaan walxaha Molybdenum waxay si sahal ah u samaysaa carbides adag, oo xasiloon oo ku jira alwaaxyada, taasoo keentay in ku dhawaad 80% sahayda molybdenum-ka aduunka loo isticmaalo wax lagu daro birta, oo ay ku jiraan {{6}xoog iyo sare{7}} alloys heerkuleed.
Inta badan xeryahooda molybdenumku wax yar bay ku milmi karaan biyaha, laakiin molybdenum{0}macdano ka kooban waxay samayn karaan ion molybdenum (MoO2−4) marka ay gaadhaan ogsijiinta iyo biyaha. Warshadaha ahaan, xeryahooda molybdenum-ka waxa loo isticmaalaa -cadaadiska iyo sare - codsiyada heerkulka, sida midabada iyo kicinta, oo xisaabiya qiyaastii 14% wax soo saarka caalamiga ah.
Marka laga soo tago codsiyadeeda warshadaha, molybdenum waa macdan raadraac lagama maarmaan u ah dhammaan noolaha eukaryotic, oo ay ku jiraan aadanaha. Waa birta leh lambarka atomiga ugu sarreeya oo ka mid ah walxaha lagama maarmaanka u ah nolosha eukaryotic. Molybdenum kala duwan -ka kooban enzymes cofactor ayaa leh hawlo kala duwan oo noolaha. Hadda, bakteeriyada qaar ayaa adeegsata molybdenum{4}} ka kooban enzymes sida kicinta ugu badan ee jebinta curaarta kiimikada ee molecules nitrogen atmospheric, taasoo awood u siinaysa hagaajinta nitrogen noolaha. Ugu yaraan 50 molybdenum - ka kooban enzymes ayaa lagu yaqaan bakteeriyada iyo xayawaanka, in kasta oo bakteeriyada iyo cyanobacterial ensaymes ay ku lug leeyihiin hagaajinta nitrogen. Molybdenum-ka ku jira nitrogenases-kan wuu ka duwan yahay kan kale ee molybdenum{9}}ka kooban ensaymes, laakiin dhamaantood waxay ka kooban yihiin molybdenum oksaydhaysan sida cofactor. Si kastaba ha ahaatee, dhammaan bakteeriyada ma isticmaasho molybdenum. Bakteeriyada iyo archaea qaarkood, tungsten, oo xubin ka ah qoyska molybdenum, ayaa ka ciyaara door jireed oo la mid ah kan molybdenum ee noolayaasha sare.
Guud ahaan, molybdenum waa curiye macdan ah oo aad u gaar ah oo leh codsiyo kala duwan. Waxay ka ciyaartaa door lama huraan ah labadaba wax soo saarka warshadaha iyo bayoolajiga.
