Isicelo seMolybdenum kunye nokwandiswa kwesayensi

I-Molybdenum yinto yentsimbi, isimboli yezinto: Mo, Igama lesiNgesi: i-molybdenum, inombolo ye-athomu 42, sisinyithi se-VIB. Ubuninzi be-molybdenum yi-10.2 g / cm 3, indawo yokunyibilika ingama-2610 ℃ kwaye indawo ebilayo yi-5560 ℃. I-Molybdenum luhlobo lwesilivere emhlophe, ilukhuni kwaye inzima, inendawo yokunyibilika ephezulu kunye nokuqhuba okuphezulu kobushushu. Ayisebenzi xa umoya ushushu. Njengento yenguqu, kulula ukutshintsha imeko yayo ioksijini, kwaye umbala we-molybdenum ion uya kutshintsha ngotshintsho lwe-oxidation. I-Molybdenum yinto ebalulekileyo yomzimba womntu, izilwanyana kunye nezityalo, edlala indima ebalulekileyo ekukhuleni, kuphuhliso nakwilifa labantu, izilwanyana kunye nezityalo. Umxholo ophakathi we-molybdenum kuqweqwe lomhlaba yi-0.00011%. Oovimba bolondolozo behlabathi be-molybdenum bamalunga nezigidi ezili-11 zeetoni, kwaye ugcino oluqinisekisiweyo lumalunga ne-19.4 yezigidi zeetoni. Ngenxa yamandla ayo aphakamileyo, indawo yokunyibilika ephezulu, ukumelana nokubola kunye nokuthamba, i-molybdenum isetyenziswa kakhulu kwisinyithi, ipetroleum, imichiza, itekhnoloji yombane kunye ne-elektroniki, amayeza kunye nezolimo. Isinyithi esine-Refractory: ukusetyenziswa kwe-molybdenum

I-Molybdenum ithatha indawo yokuqala kwimveliso yentsimbi kunye nentsimbi, igcina malunga ne-80% yokusetyenziswa ngokupheleleyo kwe-molybdenum, ilandelwe lishishini leekhemikhali, elithatha malunga ne-10%. Ukongeza, i-molybdenum ikwasetyenziswa kwitekhnoloji yombane kunye ne-elektroniki, amayeza kunye nezolimo, ukubalwa malunga ne-10% yosetyenziso lulonke.

I-Molybdenum ngoyena mthengi mkhulu wesinyithi kunye nentsimbi, kwaye isetyenziswa ikakhulu kwimveliso yentsimbi (malunga ne-43% ye-molybdenum ekusebenziseni isinyithi), i-stainless steel (malunga ne-23%), isixhobo sesinyithi kunye nesinyithi esikhawulezayo (malunga ne-8% ), I-iron cast kunye ne-roller (malunga ne-6%). Uninzi lwe-molybdenum lusetyenziswa ngokuthe ngqo ekwenzeni i-iron okanye i-iron cast emva kokuba i-molybdenum oxide briquetting, ngelixa inxenye encinci inyibilikiswa kwi-ferromolybdenum emva koko isetyenziselwa ukwenza i-iron. Njengengxubevange yentsimbi, i-molybdenum inezi zinto zilandelayo: ukuphucula amandla kunye nobulukhuni bentsimbi; ukuphucula ukuxhathisa ukubola kwensimbi kwisisombululo esisisiseko seasidi kunye nentsimbi engamanzi; ukuphucula ukunganyangeki kwentsimbi; ukuphucula ukuqina, ukuqiniswa kunye nokumelana nobushushu ngentsimbi. Umzekelo, i-stainless steel enomxholo we-molybdenum we-4% ukuya kwi-5% ihlala isetyenziswa kwiindawo ezinomhlwa kunye nokubola okunje ngezixhobo zaselwandle kunye nezixhobo zeekhemikhali.

Ingxubevange engeyiyo eyentsimbi yenziwe ngematriki ye-molybdenum kunye nezinye izinto (ezinje ngeTi, Zr, HF, W kunye re). Ezi zinto ze-alloy azidlala nje kuphela indima ekomelezeni isisombululo kunye neplastikhi yeqondo eliphantsi lobushushu be-molybdenum alloy, kodwa zikwakha isigaba se-carbide esomeleleyo nesasasazekileyo, esinokuphucula amandla kunye nokubuyisela ubushushu kwakhona kwi-alloy. I-Molybdenum esekwe kwii-alloys isetyenziswa ngokubanzi kwizinto zokufudumeza eziphakamileyo, i-extrusion abrasives, iiglasi ezinyibilikisa ii-electrode zesithando somlilo, isitshizi sokutshiza, izixhobo zokulungisa isinyithi, iinxalenye zesiphekepheke njalo njalo ngenxa yokomelela kwazo, ukuzinza koomatshini kunye nokuhamba okuphezulu.

2. Izibonelelo zeMolybdenum emhlabeni zijolise ikakhulu kumda osempuma wePasifiki, oko kukuthi, ukusuka eAlaska naseBritish Columbia ukuya eUnited States naseMexico ukuya eAndes, eChile. Uluhlu lweentaba oludumileyo ziintaba zeCordillera eMelika. Kukho inani elikhulu leediphozithi ze-porphyry molybdenum kunye ne-porphyry yeedipozithi zethusi ezintabeni, ezinje nge-clemesk kunye ne-Henderson porphyry molybdenum e-United States, elteniente kunye ne-chuki eChile I-porphyry ye-molybdenum yedipozithi e-Kamata, e-El Salvador nase-pispidaka eCanada, I-andako porphyry molybdenum idiphozithi eCanada kunye ne-hailanwali porphyry yobhedu lwe-molybdenum e-Canada, njl njl.

I-China lelinye lamazwe anezixhobo ezininzi ze-molybdenum emhlabeni. Ngokwedatha ekhutshwe liSebe lomhlaba kunye nezixhobo, ukuphela kuka-2013, i-Molybdenum yase-China yayinezigidi ezingama-26.202 zeetoni (umxholo wentsimbi). Ngo-2014, iindawo zokugcina izinto zaseTshayina iMolybdenum zonyuke nge-1.066 yezigidi zeetoni (umxholo wentsimbi), ke ngo-2014, iindawo zokugcina izinto zaseTshayina iMolybdenum ziye zafikelela kwizigidi ezingama-27.268 zeetoni (umxholo wentsimbi). Ukongeza, ukusukela ngo-2011, i-China ifumene iimayini ezintathu ze-molybdenum ezinomthamo we-2 yezigidi zeetoni, kubandakanya ukubumba igou kwiPhondo le-Anhui. Njengelona lizwe likhulu lezixhobo ze-molybdenum emhlabeni, isiseko semithombo yase China sizinzile.
