Tungsten
Tungsten yog cov hlau tsis tshua muaj. Cov hlau tsis tshua muaj feem ntau xa mus rau cov hlau uas muaj cov ntsiab lus tsawg lossis tsis tshua muaj kev faib tawm hauv qhov xwm txheej. Tungsten yog cov khoom siv dav dav, uas muaj nyob hauv yuav luag txhua hom pob zeb, tab sis nws cov ntsiab lus tsawg.
Tungsten yog ib hom hlau zoo. Raws li nws paub, cov hlau tsis tshua muaj yog cov peev txheej tseem ceeb hauv tebchaws. Tungsten yog cov hlau tsis tshua muaj, thiab nws cov ntawv thov tseem ceeb heev. Nws yog ib qho tseem ceeb ntawm cov khoom siv high-tech niaj hnub no.
3. Tungsten phaj yam ntxwv: siab melting point, siab zog thiab hardness, kev ua tau zoo ntawm qhov kub thiab txias, tsis tshua muaj resistivity, me me expansion coefficient, thiab me me hluav taws xob ua hauj lwm muaj nuj nqi.
4. Nws yog cov khoom siv hlau siv dav tshaj plaws nyob rau hauv qhov kub thiab txias. Peb lub tuam txhab tsim txhua yam ntawm daim hlau, raj, pas nrig, crucibles, ingots, thiab loj-scale tshwj xeeb-zoo li cov khoom ua los ntawm cov ntshiab tungsten, xws li hluav taws xob raj Cheebtsam, high-temperature furnace qhov chaw, high-temperature crucibles, semiconductors, teeb anode , ntau yam electrodes, iav kev lag luam qhov chaw, thermowells, ntxeem tau lub cev, thiab composites, thiab lwm yam

Tungsten phaj
tungsten phaj nqi
tungsten crucibles, tungsten raj, tungsten daim hlau, thiab tungsten-rhenium alloys yog qhov tseem ceeb ntawm sapphire siv lead ua kev loj hlob rauv thiab MOCVD; Ntau yam ntawm cov kav dej loj tungsten, mandrels, ua daim hlau thiab cov phaj pub noj yog qhov tseem ceeb ntawm cov cua kub kub xws li quartz iav furnaces; tungsten tubes, tungsten crucibles, thiab electrodes kuj tseem yog cov khoom siv tseem ceeb hauv lub ntiaj teb tsis tshua muaj kev lag luam smelting.
5. Qhov tseem ceeb tshaj plaws ntawm tungsten phaj yog tias nws muaj qhov kub thiab txias zog thiab zoo corrosion kuj rau molten alkali hlau thiab vapors. Tsuas yog thaum tungsten siab tshaj 1000 degree tuaj yeem oxide volatilization thiab kua oxide tshwm sim. Txawm li cas los xij, nws kuj muaj qhov tsis zoo ntawm qhov kub thiab txias ntawm cov yas hloov pauv thiab nyuaj rau kev ua cov yas ntawm chav tsev kub. Cov hlau refractory sawv cev los ntawm tungsten tau nquag siv hauv electronics, metallurgy, lub teeb ci, machinery, tshuaj lom neeg kev lag luam, thiab lwm yam lag luam.
