Xabagta tungsten Sare

xabagta Tungsten waxaa loo arkaa mid ka mid ah ugu madax adkaadeen fasalka walxaha imanba. Si loo siiyo sifooyinka biraha, si ay u falanqeeyaan tayada biraha laftiisa.

Features tungsten

In la fahmo muhiimadda la taaban karo ee xabagta tungsten, la soco in biraha laftiisa ayaa iska caabin ah korontada, Wehliyaha ballaarinta toosan, dhibic barafku sare.

tungsten A saafi ductility sare. biraha kala diri ee acid kaliya marka kululeeyo si heer kulka ah ^ee 5000 C. Waxa ay sameynayso la carbon, la xirrira sida wax soo saarka reaction of carbide tungsten ah. xarunta ayaa sababtay xoogga sare.

The xabagta tungsten ugu caansan - trioxide tungsten. Faa'iidada ugu weyn waa awoodda xarunta ah si loo soo celiyo biraha budo la xirrira sida by-products of oxides hoose.

Birta leeyahay cufnaanta sare, friability iyo awooda marka heerkulku hooseeyo si ay u sameeyaan xabagta tungsten.

Alloys tungsten

Seynisyahanno ku go'doonsan cayn-hal wajiga of Alloys, oo ka kooban hal ama in ka badan xubno ka. xarunta ugu fiican u yaqaan ee tungsten iyo molybdenum. Daawaha Alloying tungsten molybdenum element kordhisaa xoog siligga.

Alloys Single-waji arkaa in ay yihiin xeryahooda: tungsten - zirconium, -gafny tungsten, tungsten - niobium. ductility badnaan rhenium tungsten ku lifaaqan. waxay ku daray uusan saamayn ku lahayn waxqabadka biraha madax adkaadeen.

Diyaarinta biraha

Habka caadiga ah ma heli karaan Alloys madax adkaadeen tungsten: gaarey biraha barafku barta isla galaa qaab gas. Ujeedada ugu weyn waa diyaarinta electrolysis biraha saafi ah. In heer warshadeed aad u hesho metallurgy budada daawaha tungsten isticmaalo. Si arrintan loo sameeyo, la abuuro a shuruudaha processing gaar ah oo isticmaalaya vacuum ah.

Ahaanshaha ee dabiiciga ah

xabagta Tungsten, Waxaa iska hoogay ₃ kuwaas oo formula waa in loo gudbiyaa sida xarunta ugu sareeya. Isagu ma dhacaan ee dabiiciga ah ee ay foomka saafi, laakiin waa qayb ka mid ah senti tungsten. Geedi socodka ah ee ka fiirsato iyo processing ee biraha madax adkaadeen oo ku lug leh heerar kala duwan.

xabagta Sare ee tungsten waxaa ka soo kabsaday mass ore u. kobcinta dheeraad ah oo xarunta waa la fuliyay, iyo daaweynta la biraha saafi ah go'doon ka dib.

In habka wax soo saarka ee silig a tungsten khafiif ah daawashada si ay u gebi ahaanba laga saaro nijaasta ah. Haddii kale, sifooyinka farsamo ee alaabta la dhammeeyayna ay si weyn hoos loogu dhigi doonaa.

Meelaha isticmaalka tungsten

Sidee inuu ka soo kabsado xabagta tungsten? Hydrogen, taasoo macaamila xarunta, waxay ka caawisaa si ay u helaan bir saafi ah. Waxaa loo baahan yahay in soo saaridda ee qaybood buuxieyey, abuurista tuubooyinka X-ray, kululeeyayaasha screen iyo Foornooyinka vacuum oo prednaznachngy si loogu isticmaalo at heerkulka sare.

Steel, kuna waari dhexdeeda element ka alloying waa tungsten, lagu gartaa guryaha xoog sare. Products of daawaha sida dhigay waxaa loo isticmaalaa in soo saaridda qalabka caafimaadka, jarida qobays for ceelal shidaal qodista. Faa'iidada ugu weyn ee xarunta waxaa loo arkaa adkaysi u lahayo ku farsamaysan.

jaaniska of dhacdo in howlgalka ka mid ah dildilaac alaabta la dhammeeyayna iyo chips waa wax yar yahay. The brand ugu caansan ee steel, kuwaas oo tungsten waxaa ka mid ah, waxaa la arkaa in ay ku guuleysato.

From duugga this biraha dhif ah soo saaray Xoojiya tayo sare leh, rinjiga kala duwan, pigments gaarka ah iyo crucibles tungsten m. N. In warshadaha nukliyeerka casriga ah waxaa si balaadhan looga isticmaalo, iyo weelasha for qashinka shucaaca.

biraha refractoriness kaalin muhiim ah in alxanka ARC. Tan iyo tungsten ee foomka saafi ah waxaa loo arkaa bir dhif ah, in nidaamka diyaarinta ay u qaadaan kobcinta iyo dib ore tungsten ah. In foomka saafi ah waxa uu leeyahay midab khafiif ah cirradayda luster ah macdan ah dabeecad u. Alloys tungsten Standard, loo yaqaan stellite, ayaa sidoo kale ka kooban Cobalt iyo chromium. qaybaha ugu muhiimsan ee xeryahooda sida adeegta Cobalt. Alloys yihiin in baahida injineernimada farsamada.

oxides tungsten

Waa maxay leedahay xabagta gaar tungsten (6), ee caanaha ah taas oo uu leeyahay qaab hoogay _3? Birta muujiyaan karaa dalalka qayilo kala duwan: xasilloonida ugu badan yihiin kala duwanaanshuhu la biraha valence (4) iyo (6). Waxaa iska hoogay xiriir horeysay nooca _{2aad ee} la xidhiidha oxides acidic iyo leedahay sifooyinka soo socda: dhibic barafku sare iyo cufnaanta gaar ah. xarunta kiimikada Tani waa ku dhawaad beelaya biyo, laakiin markii kululeeyo waxaa la kala diri karaa acids iyo alkalis. In warshadaha kiimikada waxaa loo adeegsanayaa sidii qaar kaaliya in dareen diidmo qaar ka mid ah. Tusaale ahaan, sii labanlaabi hoogay ₂ isticmaalaa in soo saaridda ee alaabta dhoobada.

xabagta Tungsten isagoo valence ah (6) sidoo kale muujinayaa sifo guryaha acidic. Xarunta Tani waxaa ka jawaabay alkalis, laakiin aan awood u kala diridda ee biyaha. Marka la eego in xarunta dhibic barafku sare, waxaa loo isticmaalaa oo kaliya sida hababka kiimikada xawaaraha ah.

gunaanad

In koorsada of chemistry imanba diiradda on daraasadda of oxides, falanqaynta ee guryaha iyo warshadaha sifooyinka primeneniyav. Tusaale ahaan, in shaqada imtixaan final fasalka sagaalaad dalab soo socota: "koobanahay oxides copper Formula, bir iyo tungsten, iyo sidoo kale loo ogaado guryaha ay kiimikada ee aasaasiga ah."

Si aad u guul leh ula qabsadaan hawsha, waa in aad hayso wax fikrad ah oo ka mid ah muuqaalada oxides ah. Waxaa loo tixgeliyaa kuwa xeryahooda binary, taas element labaad waa oxygen. All oxides loo kala saaro saddex kooxood: aasaasiga ah, acidic, amphoteric.

Iron iyo copper yihiin xubno ka mid ah group-guurka, sidaas waxay noqon kartaa mid ka mid ah valence variable. Waayo, copper loo qori karaa kaliya labo fursadaha oxides soo bandhigista guryaha aasaasiga ah - CU ₂ O iyo CuO.

Iron ma aha ee sub-group weyn ee xubno ka kiimikada, sidaas darteed waxaa jira gobolka qayilo ka +2 iyo +3. Xaaladahan, noocyada soo socda ee oxides loo sameeyay - Feo iyo Fe ₂ O _3.

Tungsten in xeryahooda binary la oxygen in inta badan teedu valence (4) iyo (6). Labada of xabagta biraha muujiyaan guryaha acidic, si ay waxaa loo isticmaalaa in industry sida Sheelare hababka kiimikada.

Ujeedada ugu weyn ee oxides tungsten waa go'doon ah oo ka mid ah biraha saafi ah in dalabka ee warshadaha kiimikada iyo qodniinka-.
