Higher Tungsten oxide

Tungsten oksayidi njengenye yezona eliyinjubaqa eklasini kwezinto ezingaphiliyo. Ukuze anike iimpawu intsimbi, ukuhlalutya umgangatho metal ngokwayo.

Iimpawu Tungsten

Ukuze siqonde ukubaluleka bobuqili Tungsten oxide, qaphela ukuba metal ngokwayo une ukumelana zombane, ukungavumelani kwe ukwandiswa yomgama, eyona zavuleka.

A Tungsten olunyulu ductility eliphezulu. I-metal ichithwe kwi acid kuphela xa itshiswe ukuya kwiqondo ^lobushushu 5000 C. idityaniswe carbon, ukwakha njengoko imveliso indlela Tungsten khabhayithi. Umchiza Umphumela uye amandla aphezulu.

Eyona ixhaphakileyo oxide Tungsten - trioxide Tungsten. Uncedo engundoqo ukukwazi yikhompawundi ukubuyisela umgubo wentsimbi bokwakha njengokuba ngu-imveliso oxides asezantsi.

Metal has ezixineneyo, friability kunye nokukwazi kumaqondo obushushu aphantsi ukwakha oxide Tungsten.

aluminiyamu Tungsten

Izazinzulu ziye bodwa iintlobo ezi-aluminiyamu, nto leyo yakhiwa izakhi omnye okanye ngaphezulu. Eyona kakuhle ambaxa Tungsten kunye molybdenum. Yenza ingxubevange Alloying isiqalelo molybdenum Tungsten kwandisa uqine.

aluminiyamu-Isigaba esinye zithathwa ukuba iikhompawundi: Tungsten - zirconium, Tungsten -gafny, Tungsten - ukrweco. ductility obukhulu Tungsten oluLula apha. Yokuyifaka awukuchaphazeli ukusebenza metal eliyinjubaqa.

Ukulungiswa metal

Inkqubo eqhelekileyo ayikwazi kufumana aluminium Tungsten eliyinjubaqa; efikelela ukunyibilika indawo metal nangoko ingena uhlobo sukube. Eyona njongo iphambili kumalungiselelo electrolysis metal ecocekileyo. Xa ngezinga mveliso ukufumana Tungsten ingxubevange umgubo yokunyibilikisa isinyithi kusetyenziswa. Ukuze wenze oku, ukudala iimeko ezizodwa inkqubo usebenzisa cleaner.

Ukuba indalo

Tungsten oxide, utshelwe ₃ ogama yokubala ibizwa ngokuba compound liphezulu. Yena awufumaneki lwendalo uhlobo yayo esulungekileyo, kodwa yinxalenye ores Tungsten. Inkqubo le gesi kunye nokuqhutywa metal eliyinjubaqa ibandakanya izigaba ezininzi.

oksayidi Higher of Tungsten liqokelelwa intlama ore. Eminye nokwandiswa umchiza kuliwa, yaye emva unyango zesinyithi ecocekileyo ekwanti.

Xa inkqubo yokuvelisa ucingo Tungsten obhityileyo ebukele ukuze ukususa ngokupheleleyo ukungcola. Kungenjalo, iimpawu zobugcisa mveliso ogqityiweyo ziza kuncitshiswa kakhulu.

Iindawo lokusebenzisa Tungsten

Indlela ukubuyisa Tungsten oxide? Hydrogen, esinxibelelana ezimbaxa, kuyanceda ukufumana metal ecocekileyo. Kufuneka ekwenziweni imisonto filament, ukudala iityhubhu X-ray, izifudumezi screen kunye amaziko cleaner leyo prednaznachngy ukusetyenziswa kwiqondo lobushushu eliphezulu.

Steel, apho element alloying na Tungsten, ebonakala ngeempawu aphezulu ngamandla. Iimveliso ezenziwe ingxubevange eso sisetyenziselwa ekwenziweni izixhobo zonyango, nangokukrola ifaka kuzo imithombo wokugrumba. Inzuzo ephambili compound ithathwa ukumelana deformation ngoomatshini.

Ngenene ingenzeka xa ukusebenza neentanda imveliso igqityiwe kunye neetships luphantsi kakhulu. Uhlobo uthandwayo ngentsimbi, apho Tungsten ibandakanyiwe, loo nto ithathwa ukuphumelela.

Ukususela kule scrap metal enqabileyo zavelisa ehlanganisa kwizinga eliphezulu, iipeyinti ezahlukeneyo, zombala ezizodwa kunye crucibles Tungsten N. Kushishino yenyukliya mihla isetyenziswa ngokubanzi m. Neenkonkxa zokulahla inkunkuma eqhumayo.

metal refractoriness kudlala indima ebalulekileyo arc. Ekubeni Tungsten ngohlobo olunyulu kugqalwa metal enqabileyo, nangokwenkqubo yawo ukulungiselela lwenziwa nokusebenzisa kurisayikilishwe nsimbi Tungsten. Ngendlela esulungekileyo inombala ukukhanya nozithobela into ebuntsimbi ayenechaphothi isici. aluminiyamu Tungsten Standard, obizwa ngokuba stellite, nazo ziquka ayibe kunye chromium. Icandelo iphambili iikhompawundi ezifana ikhonza ayibe. Aluminiyamu zifunwa sobunjineli ngoomatshini.

oxides Tungsten

Yintoni na oksayidi ingakumbi Tungsten (6), indlela apho na uhlobo _utshelwe-3? Metal unako ukubonisa igcwala ithi ezahlukeneyo: uzinzo A ezahlukeneyo kunye Valence metal (4) kunye (6). Utshelwe uhlobo lokuqala uqhagamshelo ₂ inxulumene oxides emuncu kwaye ezi mpawu zilandelayo: eyona yokunyibilika kunye mninzi ethile. Le compound chemical phantse ezingenakunyibilika emanzini kodwa xa itshiswe songanyibilikisswa asidi alkalis. Kushishino chemical usetyenziswa njengesixhobo kwezinye ngayo. Umzekelo, yeha _ama-2 ezisetyenziswa xa kusenziwa imveliso yodongwe.

Tungsten oksayidi ukuba Valence of (6) Kwakhona ivelisa luphawu iipropati emuncu. Le ephindeneyo awasabela ngayo kunye alkalis, kodwa ayikwazi ezinyibilikayo emanzini. Sisazi ukuba enyibilikayo indawo compound ephakamileyo, isetyenziswa kuphela xa kukho iinkqubo namafutha chemical.

isiphelo

Ekuhambeni zemichiza ezingaphiliyo lujolise ekufundeni oxides, uhlalutyo iimpawu zazo kunye noshishino neempawu primeneniyav. Umzekelo, kuviwo lokugqibela ugrade lesithoba umsebenzi sipho lulandelayo: "Qamba oxides Formula nobhedu, nesinyiti kunye Tungsten, kwaye amisele iimpawu zazo ezisisiseko chemical."

Ukuze ukumelana ngempumelelo umsebenzi, kufuneka ube ingcinga yokuba iimpawu oxides. Ingqalelo ezo iikhompawundi zokubini, apho element yesibini i-oksijini. Zonke oxides lokuhlela ngokwamaqela amathathu: basic, asidi, amphoteric.

Yintsimbi nobhedu imiba kwiqela lenguqu, ngoko unokuba Valence bume. Ngokuba nobhedu na kubhalwa ezimbini kuphela iinketho oxides bembonisa iipropati ezisisiseko - Cu ₂ O no Čuo.

Iron ayikho main sub-iqela imichiza, ngoko kukho igcwala karhulumente-phinde ngo 2 no +3. Kule meko, ezi ndidi zilandelayo oxides kwakheka - feo kunye Fe _{2 O-3.}

Tungsten xa iikhompawundi yokubini kunye oksijini kakhulu ubonisa Valence (4) kunye (6). Zombini i oxide metal ukubonisa iipropati emuncu, ngoko zisetyenziswa kushishino njengoko accelerators iinkqubo imichiza.

Eyona njongo ephambili yale oxides Tungsten ukuba nesizungu ezi metal ecocekileyo ezifunwayo kumashishini yemichiza metallurgical.
