Molybdenum ngwa na sayensị popularization

Molybdenum bụ ihe eji eme igwe, akara mmewere: Mo, Aha Bekee: molybdenum, nọmba atọmịk 42, bụ VIB metal. Njupụta nke molybdenum bụ 10.2 g / cm 3, ebe agbaze bụ 2610 ℃ na ebe isi ọkụ bụ 5560 ℃. Molybdenum bụ ụdị ọlaọcha na-acha ọcha ọla, siri ike ma sie ike, na ebe agbaze dị elu na nrụpụta ọkụ dị elu. Ọ naghị eme ikuku na ọnọdụ okpomọkụ. Dị ka ihe mgbanwe, ọ dị mfe ịgbanwe ọnọdụ ọxịdashọn ya, na agba nke molybdenum ion ga-agbanwe na ngbanwe ọnọdụ ọxịdashọn. Molybdenum bu ihe di nkpa banyere aru mmadu, anumanu na osisi, nke n’eme ihe di nkpa n’ime oganihu, mmepe na ihe nketa nke mmadu, anumanu na osisi. Onu ogugu nke molybdenum di na ala bu 0,00011%. Ihe ndebe molybdenum zuru ụwa ọnụ nwere ihe dị ka nde tọn iri na otu, ihe ndị egosiri pụtara ihe ruru nde tọn 19.4. N'ihi ike ya dị elu, agbaze agbaze elu, nguzogide corrosion na iyi mgbochi, a na-ejikarị molybdenum eme nchara, mmanụ ala, kemịkalụ, teknụzụ eletriki na teknụzụ, ọgwụ na ọrụ ugbo. 3 refractory metal: ngwa nke molybdenum

Molybdenum nwere ọnọdụ mbụ na ụlọ ọrụ ígwè na ígwè, na-edekọ ihe dịka 80% nke ngụkọta nke molybdenum, na-esote ụlọ ọrụ kemịkalụ, na-ede ihe dịka 10%. Tụkwasị na nke ahụ, a na-ejikwa molybdenum na teknụzụ eletriki na eletriki, nkà mmụta ọgwụ na ugbo, na-atụle ihe dịka 10% nke mkpokọta oriri.

Molybdenum bụ onye na-azụ igwe na ígwè na nke kachasị ukwuu, a na-ejikwa ya na mmepụta nke ígwè alloy (ihe dị ka 43% nke molybdenum na ngụkọta nchara ígwè), igwe anaghị agba nchara (ihe dị ka 23%), nchara igwe na ngwa nchara dị elu (ihe dịka 8%) ), igba ígwè na ala (banyere 6%). A na-ejikarị molybdenum eme ihe nchara ma ọ bụ nkedo ígwè mgbe ụlọ ọrụ molybdenum oxide briquetting, ebe obere akụkụ gbazee n'ime ferromolybdenum wee jiri ígwè mee. Dịka alloy element of steel, molybdenum nwere uru ndị a: ịkwalite ike na ịdị ike nke ígwè; imezi emebi corrosion eguzogide nke ígwè na acid-isi ngwọta na mmiri mmiri metal; imezi uwe mgbochi nke ígwè; imeziwanye hardenability, weldability na iguzogide okpomọkụ nke ígwè. Dịka ọmụmaatụ, igwe anaghị agba nchara nwere ọdịnaya molybdenum nke 4% - 5% a na-ejikarị ya eme ihe na ebe dị njọ na nrụrụ, dị ka akụrụngwa mmiri na akụrụngwa kemịkal.

Ngwunye na-abụghị nke nwere ihe mejupụtara molybdenum matriks na ihe ndị ọzọ (dị ka Ti, Zr, HF, W na re). Ihe ndị a nwere ọ bụghị naanị na-arụ ọrụ na mgbatị ume na obere okpomọkụ nke molybdenum alloy, kamakwa na-etolite usoro carbide siri ike ma gbasasịa, nke nwere ike melite ike na recrystallization okpomọkụ nke alloy. A na-ejikarị alloys ndị nwere Molybdenum eme ihe dị elu na ihe ndị na-ekpo ọkụ ọkụ, ihe nkedo extrusion, iko ọkụ na-agbaze iko, mkpuchi mkpuchi, ihe ndị na-arụ ọrụ ígwè, akụkụ ụgbọelu na ihe ndị ọzọ n'ihi ezigbo ike ha, nkwụsi ike na nnukwu ductility.

2. Molybdenum akụrụngwa dị na ụwa na-elekwasị anya n'akụkụ ọwụwa anyanwụ nke Pacific Basin, ya bụ, site na Alaska na British Columbia site na United States na Mexico ruo Andes, Chile. Ugwu ugwu ama ama bu ugwu Cordillera di na Amerika. E nwere ọnụ ọgụgụ dị ukwuu nke porphyry molybdenum na porphyry ọla kọpa na ugwu, dị ka clemesk na Henderson porphyry molybdenum ego na United States, elteniente na chuki na Chile The porphyry copper molybdenum na-etinye na Kamata, El Salvador na pispidaka na Canada, andako porphyry molybdenum nkwụnye ego na Canada na hailanwali porphyry ọla kọpa molybdenum nkwụnye ego na Canada, wdg China bụkwa ọgaranya molybdenum ego, na Henan, Shaanxi na Jilin ógbè aza ajụjụ maka 56.5% nke ngụkọta ego nke molybdenum ego na China.

China bu otu mba nwere oke molybdenum nke di na uwa. Dabere na data ndị Mịnịstrị na-ahụ maka ala na akụrụngwa wepụtara, ka ọ na-erule ngwụsị afọ 2013, Molybdenum nke China dị nde tọn 26.202 (ihe ọla) Na 2014, ala Molybdenum nke China rịrị site na 1.066 nde tọn (ọdịnaya ọla), yabụ site na 2014, Molybdenum nke China eruola nde tọn 27.268 (ọdịnaya ọla). Tụkwasị na nke a, kemgbe 2011, China achọpụtawo mines molybdenum atọ nwere ikike nke nde 2, gụnyere shapinggou na mpaghara Anhui. Dịka mba kachasị ukwuu nke akụ molybdenum na ụwa, isi mmalite akụ nke China kwụsiri ike karị.
