Muaj qhov siab tshaj plaws melting point ntawm cov hlau paub, ntawm 6192 ° F, pom tseeb tias tungsten yuav yog nyuaj rau yaj Hauv kev xav, txhua yam tuaj yeem yaj yog tias koj siv cov cua sov txaus.. … Qhov tsuas paub lub ntsiab lus uas muaj melting point ntau dua tungsten yog carbon, ntawm 6422 ° F (3550 ° C).

Tungsten puas tuaj yeem yaj tau?

Tungsten paub tias yog ib qho nyuaj tshaj plaws nyob rau hauv qhov xwm txheej. Nws yog super ntom thiab yuav luag tsis tuaj yeem yaj. Ntshiab tungsten yog cov hlau dawb-dawb thiab thaum ua rau hauv cov hmoov zoo tuaj yeem ua rau tawg thiab tuaj yeem ua rau hluav taws kub ceev.

Nws raug nqi npaum li cas rau yaj tungsten?

5 Teb. Tungsten lub melting point ntawm 3422 ° C yog qhov siab tshaj plaws ntawm tag nrho cov hlau thiab thib ob tsuas yog carbon (3550 ° C) ntawm cov khoom. Qhov no yog vim li cas tungsten siv nyob rau hauv foob pob ua ntxaij nozzles thiab reactor linings.

Vim li cas tungsten melting point siab heev?

Tungsten muaj qis tshaj coefficient ntawm thermal expansion ntawm cov hlau ntshiab. Qhov qis thermal expansion thiab siab melting point thiab tensile lub zog ntawm tungsten originate los ntawm muaj zog hlau bonds tsim ntawm tungsten atoms los ntawm 5d electrons.

Dab tsi yog cov hlau uas muaj zog tshaj plaws hauv ntiaj teb?

Tungsten muaj lub zog tensile siab tshaj plaws ntawm cov hlau ntshiab - txog li 500,000 psi ntawm chav tsev kub. Txawm tias qhov kub siab tshaj 1,500 ° C, nws muaj lub zog tensile siab tshaj plaws. Txawm li cas los xij, tungsten hlau yog nkig, ua rau nws siv tsawg dua hauv nws lub xeev ntshiab.
