Amaqiniso nezibalo ze-Molybdenum
I-Molybdenum: Yinto eyenzeka ngokwemvelo ekhonjwe ngo-1778 nguCarl Wilhelm Scheele, usosayensi waseSweden naye owathola umoya-mpilo emoyeni. Inelinye lamaphuzu ancibilikayo aphezulu kakhulu kuzo zonke izakhi nokho ukuminyana kwayo kungama-25% kuphela ensimbi enkulu. Iqukethwe kuma-ores ahlukahlukene, kepha i-molybdenite kuphela ...Funda kabanzi -
I-Tungsten isotope isiza ukufunda ukuthi ungawavikela kanjani ama-fusion reactor azayo
Ingaphakathi le-nuclear fusion energy reactors esizayo lizoba phakathi kwezindawo ezinonya kakhulu ezake zakhiqizwa eMhlabeni. Yini eqine ngokwanele ukuvikela ingaphakathi le-reactor ehlanganisiwe kusukela ekushiseni okukhiqizwe yi-plasma okufana nezithutha zasemkhathini ezingena kabusha emkhathini woMhlaba? Abacwaningi be-ORNL u...Funda kabanzi -
Abacwaningi babona ukwakheka kokuqhekeka ku-tungsten ephrintiwe engu-3-D ngesikhathi sangempela
Njengoba izigqaja ngamaphuzu aphakeme kakhulu ancibilikayo nabilayo azo zonke izakhi ezaziwayo, i-tungsten isiphenduke into ethandwayo ezisetshenziswayo ezibandakanya amazinga okushisa adlulele, okuhlanganisa imicu ye-lightbulb, i-arc welding, i-radiation shielding futhi, muva nje, njengezinto ezibhekene ne-plasma kuma-fusion reactor afana ne-. ..Funda kabanzi -
I-Weldability ye-Tungsten kanye nama-alloys ayo
I-Tungsten nama-alloys ayo ingahlanganiswa ngempumelelo nge-gas tungsten-arc welding, i-gas tungsten-arc braze welding, i-electron beam welding kanye ne-chemical vapor deposition. Ukushisela kwe-tungsten kanye nenani lama-alloys ayo ahlanganiswe i-arc casting, i-powder metallurgy, noma i-chemical-vapor depositi...Funda kabanzi -
Indlela yokwenza i-Tungsten Wire?
Ukwenza i-tungsten wire kuyinqubo eyinkimbinkimbi, enzima. Inqubo kumele ilawulwe ngokuqinile ukuze kuqinisekiswe i-chemistry efanele kanye nezakhiwo ezifanele zomzimba zocingo oluphelile. Ukunqamula amakhona kusenesikhathi ngenqubo yokunciphisa amanani entengo kungaholela ekusebenzeni kabi kwe-fin...Funda kabanzi -
Intengo ye-Tungsten Yase-China Yayisethrendini Ephezulu Maphakathi noJulayi
Intengo ye-tungsten yase-China ibilokhu inyuka ngeviki eliphele ngoLwesihlanu zingama-17 kuJulayi, 2020 ngemuva kokwethenjwa kwemakethe okuthuthukisiwe kanye nokulindela okuhle kokuhlinzekwa kanye ne-de sides. Kodwa-ke, uma kucatshangelwa ukungazinzi emnothweni kanye nesidingo esibuthakathaka uma kuqhathaniswa, amadili anzima ukwanda esikhathini esifushane...Funda kabanzi -
Izakhiwo zemishini yezintambo ze-tungsten ngemuva kokwelashwa kokuhamba ngebhayisikili
1. Isethulo Izintambo ze-Tungsten, ezinogqinsi olusuka emashumini ambalwa kuya emashumini ama-micro- metres, zenziwa ngokwepulasitiki zibe ama-spirals futhi zisetshenziselwa imithombo yokukhanya ecwebezelayo kanye nokukhipha ukukhanya. Ukwenziwa kocingo kusekelwe kubuchwepheshe bempushana, okungukuthi, impushana ye-tungsten etholakala ngenqubo yamakhemikhali...Funda kabanzi -
I-Tungsten ingase ingabi ishothi ehamba phambili yokwenza izinhlamvu 'eziluhlaza'
Njengoba kunemizamo eyenziwayo yokuvimbela izinhlamvu ezisekelwe kumthofu njengengozi engaba yingozi empilweni nakwezemvelo, ososayensi babika ubufakazi obusha bokuthi enye into eyinhloko yezinhlamvu zezinhlamvu - i-tungsten - ingase ingabi indawo enhle. ...Funda kabanzi -
Ucwaningo luhlola i-tungsten ezindaweni eziyingozi kakhulu ukuze kuthuthukiswe izinto zokuhlanganisa
I-fusion reactor ibhodlela kazibuthe eliqukethe izinqubo ezifanayo ezenzeka elangeni. Amafutha e-Deuterium kanye ne-tritium ayahlangana ukuze akhe umhwamuko wama-ion we-helium, ama-neutron nokushisa. Njengoba le gesi eshisayo, ene-ionized—ebizwa ngokuthi i-plasma—ivutha, lokho kushisa kudluliselwa emanzini ukuze kwenziwe isitimu ukuze kuphendulwe izinjini zomoya...Funda kabanzi -
Ukusuka ku-cobalt kuye ku-tungsten: ukuthi izimoto zikagesi nama-smartphones zivusa kanjani uhlobo olusha lokujaha igolide
