Zirconium-tungsten tswj kev hloov kho tshiab: Leej twg yuav dhau los ua Txoj Haujlwm B hauv thaj tsam ntawm semiconductors thiab nuclear zog?

Nrog rau kev siv zog ntawm kev tiv thaiv kev tiv thaiv thoob ntiaj teb, hauv thawj peb lub hlis twg ntawm 2026, kev xa tawm quotas thiab kev siv tswj ntawm Zirconium thiab Tungsten tau nkag mus rau theem tsis tau muaj dhau los. Raws li lub hauv paus ntawm nuclear reactor structural cov ntaub ntawv thiab precision machining "industrial hniav", cov khoom sib txawv ntawm ob hom hlau no yog yuam downstream industries nrhiav kev ua tau zoo - lub rooj ntev zaum - cim lwm txoj kev.

Nyob rau hauv lub siab ntawm "tswj zirconium thiab limiting tungsten", lub refractory hlau kev lag luam tab tom hloov pauv loj ntawm cov ntaub ntawv coj los ntawm niobium, tantalum, thiab molybdenum.

1. Hloov cov zirconium (Zr): Cov khoom ntawm niobium (Nb) thiab titanium alloys overlap Zirconium yeej ib txwm yog tib txoj kev xaiv rau nuclear roj cladding hlab vim nws tsis tshua muaj thermal neutron absorption cross section.Txawm li cas los xij, nyob rau hauv kev tswj hwm, cov chaw tshawb fawb tshawb fawb tau nrawm rau kev txheeb xyuas lwm txoj hauv kev:

Kev nce ntawm Niobium: Hauv kev ua haujlwm ntawm superconductivity thiab superalloys, Niobium muaj cov qauv lattice zoo sib xws rau zirconium. Rau cov khoom uas tsis yog -nuclear corrosion- cov khoom siv tiv taus, cov niobium ntshiab thiab niobium-hafnium alloys yog hloov cov ntaub ntawv zirconium rau cov kua qaub muaj zog. Txawm hais tias cov neutron ntes hla ntu ntawm niobium siab dua li ntawm zirconium, niobium-raws li alloys pom zoo siab dua -kub creep zog hauv chav kuaj- qib me me reactors thiab cov cua sov tshwj xeeb- cov khoom tiv thaiv.

Kev ruaj ntseg siab titanium alloy (Ti-Al-Sn): Hauv thaj chaw tshuaj tiv thaiv- corrosion, titanium alloys nrog tshwj xeeb proportions yog maj mam hloov cov ntaub ntawv zirconium. Txawm hais tias nws qhov kev ua tau zoo nyob rau hauv hydrochloric acid yog me ntsis qis dua ntawm zirconium, los ntawm kev polishing nto thiab passivation technology, titanium alloy muaj peev xwm npog 85% ntawm cov pej xeem thiab kev ua neej daim ntawv thov scenarios ntawm zirconium.

2. Hloov cov tungsten (W): kev faib ua haujlwm zoo ntawm molybdenum (Mo) thiab tantalum (Ta).

Tungsten yog cov hlau uas muaj cov ntsiab lus melting, thiab nws cov kev tswj tau cuam tshuam ncaj qha rau cov semiconductor evaporation, siab -kub rauv thermal field thiab cemented carbide cuab tam industries.

Molybdenum (Molybdenum) ntxiv: Molybdenum thiab tungsten muaj nyob rau hauv tsev neeg Kyanite, nrog rau qhov chaw melting mus txog 2623 degree. Hauv kev ua haujlwm ntawm lub tshuab nqus tsev thermal evaporation, molybdenum nkoj thiab molybdenum crucibles tau pib hloov cov khoom tungsten rau ntawm qhov loj Txawm hais tias qhov kev txwv siab ntawm cov cua sov ntawm molybdenum qis dua li ntawm tungsten, hauv kev lag luam hauv qab 1800 degree, molybdenum tau dhau los ua tus nqi zoo dua -

Dimensional collapse strike ntawm Tantalum (Tantalum): Nyob rau hauv lub tshav kub ntawm electron beam cua sov thiab siab -precision nyias zaj duab xis, thaum cov khoom ntawm tungsten xov hlau txwv, Tantalum ntawv ci thiab Tantalum ib tug siv lead ua yog ib qho tseem ceeb dua vim lawv zoo electron emission efficiency thiab tsis tshua muaj siab tawm - gassing tus nqi. High -kawg lwm txoj rau semiconductor ntim thiab kuaj.

3. Kev hloov kho thev naus laus zis "tungsten txo" hauv kev ua haujlwm ntawm cemented carbide tungsten yog lub hauv paus ntawm cemented carbide. Raws li kev tswj hwm yav dhau los tam sim no, kev lag luam tau hloov mus rau "cermet" thiab "tungsten-dawb cemented carbide":

Titanium carbide (TiC)-raws li cemented carbide: Lub chaw kuaj yog siv nickel- molybdenum (Ni-Mo) ua cov ntaub ntawv txhawm rau txhawm rau ua kom muaj zog ntawm cov cuab yeej titanium carbide, sim vam khom rau tungsten carbide (WC) hauv kev kub ceev {{3}

4. 2026 Supply Chain Early Warning: Linkage Effects of Alternative

Cov kws tshaj lij kev lag luam cov ntaub ntawv tau taw qhia tias kev hloov khoom siv tsis yog ib qho yooj yim "hloov A rau B", tab sis kev tsim kho ntawm cov txheej txheem ntws.

Tus nqi hloov pauv: Nrog rau kev tswj hwm ntawm zirconium thiab tungsten, muaj kev thov loj rau niobium thiab tantalum kev lag luam, uas tau ua rau tus nqi ntawm tantalum concentrate nce li ntawm 8% thaum ntxov 2026.

Cov txheej txheem kev teeb tsa: Cov txheej txheem kev ua haujlwm ntawm lwm cov ntaub ntawv (xws li niobium khob thiab tantalum nkoj) txawv ntawm cov qub zirconium-tungsten qhov chaw. Cov tuam txhab lag luam yuav tsum tau ua cov thermal teb simulation thiab ntsuas cov txiaj ntsig sai li sai tau.

5. Koj cov khoom siv saw hlau muaj nyob rau hauv qhov chaw

Siab -puritymolybdenum nkoj/ molybdenum sawb: qhov chaw txhawb nqa, kub tsis kam 2600 degree.

Precisiontantalum ntawv ci/ niobium khob: customized rau chav kuaj, muab MTC cov ntaub ntawv.
