Kwerekana ibicuruzwa
Nkicyuma kitagira amabara, tungsten ifite imbaraga nini cyane.Kubera iyi 2.Ibiranga byinshi, karubide ya tungsten ifite ubukana bwinshi kandi irwanya kwambara yakoreshejwe mubikoresho byo gutema nibikoresho byo gucukura ku rugero runini.
Tungsten nicyuma cyangiritse gifite aho gishonga cyane.Ibyuma rusange bifite aho bishonga birenga 1650 ℃ hamwe nububiko runaka hamwe nugushonga gusumba aho gushonga kwa zirconium (1852 ℃) byitwa ibyuma bivunika.Ibyuma bisanzwe bivunika ni tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium, na titanium.Nkicyuma cyangiritse, inyungu yingenzi ya tungsten nuko ifite imbaraga zubushyuhe bwo hejuru hamwe no kurwanya ruswa nziza kumashanyarazi ya alkali yashizwemo numwuka.Bigaragara hejuru ya 1000 ℃.Molybdenum na tungsten bifite ibintu bisa cyane, ahantu hagaragara cyane no gutwarwa n amashanyarazi, coefficente ntoya yo kwagura ubushyuhe bwumuriro, kandi byoroshye gutunganya kuruta tungsten.
Ubushyuhe bwumuriro wicyuma cya molybdenum [135 watts / (m · fungura)] gikora neza hamwe nubushyuhe bwihariye [0.276 kJ / (kg · gufungura)], bigatuma ihitamo bisanzwe birwanya ihungabana ryumuriro numunaniro ukabije.Ikibanza cyacyo cyo gushonga ni 2620 ℃, icya kabiri kugeza tungsten na tantalum, ariko ubucucike bwayo buri hasi cyane, kubwibyo imbaraga zayo (imbaraga / ubucucike) iruta tungsten, tantalum nibindi byuma, bigira akamaro cyane mubisabwa bifite uburemere bukomeye busabwa.Molybdenum iracyafite ubukana bwinshi kuri 1,200 ℃.
Ibyingenzi
Tungsten ifite aho ishonga cyane, umuvuduko ukabije wumuyaga, nigipimo gito cyo guhumeka.Imiterere yimiti ya tungsten irahagaze neza, ntishobora gukoreshwa numwuka namazi mubushyuhe bwicyumba, ntigishobora gukomera muri aside hydrochloric, aside sulfurike, aside nitricike nigisubizo cya alkali.Kunyunyuza mumazi yumwami hamwe nuruvange rwa acide nitric na aside hydrofluoric.Ku bushyuhe bwinshi, irashobora guhuza na chlorine, bromine, iyode, karubone, azote, sulfure, ariko ntibishobora gukoreshwa na hydrogenation.Ahantu ho gushonga kwa tungsten igera kuri 3410 ℃, iracyafite imbaraga nyinshi kuri 1300 ℃, mugihe amavuta ashingiye kuri tungsten nayo afite imbaraga nyinshi nka 1800 ℃ kandi ifite imbaraga zo kurwanya ingaruka ziterwa nubushyuhe.
Gusaba ibicuruzwa
Bitewe n'ubucucike bwinshi bwa tungsten, Ubukomere Bwinshi, Rero, byahindutse ibikoresho byiza byo gukora amavuta yihariye ya rukuruzi, Izi mvaruganda zidasanzwe zikomeye zigabanyijemo W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag nizindi serie nkuru, Ubu bwoko bwa alloy bufite2. Ibyingenzis yikigereranyo kinini, imbaraga nyinshi, imbaraga zikomeye zo kwinjiza imishwarara, ubwinshi bwumuriro wumuriro, coefficente ntoya yo kwagura ubushyuhe, amashanyarazi meza, gusudira no gutunganya neza, Irakoreshwa cyane mukirere, indege, igisirikare, gucukura peteroli, ibikoresho byamashanyarazi, ubuvuzi nibindi inganda, nko gukora ibirwanisho, ubushyuhe, kugenzura ingero zingana ninyundo hamwe nibikoresho byoguhuza nkicyuma cyuma, icyuma kizunguruka, icyuma cyo gusudira electrode, nibindi.
Umwanya wa elegitoroniki
Tungsten ifite plastike ikomeye, umuvuduko muto wo guhumeka, ahantu ho gushonga cyane hamwe nubushobozi bukomeye bwo kohereza imyuka ya elegitoronike, bityo tungsten hamwe nudusimba twayo bikoreshwa cyane mubikorwa bya elegitoroniki n’amashanyarazi.Kurugero, insinga ya tungsten ifite umuvuduko mwinshi nubuzima bwa serivisi ndende, bityo ikoreshwa cyane mugukora filament zitandukanye, nk'itara ryaka, itara rya iyode, itara rya tungsten naryo rishobora gukoreshwa mugukora cathode ishyushye kandi irembo rya elegitoroniki oscillator hamwe nibikoresho bitandukanye bya elegitoronike kuruhande rwa hoteri ya cathode.Uwiteka2. Ibyingenzis ya tungsten ituma nayo ibereye gusudira TIG nibindi bikoresho bya electrode kubikorwa bisa.
Inganda zikora imiti
Ibikoresho bya Tungsten bikoreshwa cyane nka catalizator hamwe namabara adasanzwe, nka tungsten disulfide ikoreshwa nka lubricant na cataliste muri lisansi yubukorikori, okiside ya bronze ya tungsten ikoreshwa mumashusho, calcium cyangwa magnesium tungsten ikoreshwa muri fosifore.
Utundi turere
Kuberako tungsten isa na boryl silikate yikirahure, ikoreshwa mugukora ibirahuri cyangwa kashe.Tungsten ifite sensibilité nkeya kandi ikoreshwa mugukora ubuziranenge bwa tungsten imitako ya zahabu.Byongeye kandi, tungsten ikoreshwa no mubuvuzi bwa radio, kandi ibikoresho bimwe na bimwe bizakoresha insinga ya tungsten.
