Tungten yog ib txwm nyiaj - grey lossis grey, tab sis lwm yam xim tuaj yeem tshwm sim.
1. Cov xim ntawm tungsten
Tungsten yog xim hlau, ib txwm nyiaj - grey lossis grey. Txawm li cas los xij, thaum melted thiab txias ntawm cov xim kub, nws tuaj yeem tsim cov xim ntau, xws li xiav, xim ntsuab, xim av, lossis xim dub. Cov xim no muaj tshwm sim los ntawm cov tebchaw ntawm tungsten oxides thiab lwm yam tshuaj lom neeg.
2. Vim li cas rau tungsten tus xim
Tungsten cov xim yog nyob ntawm lub℃thiab concentration ntawm nws cov oxides thiab lwm yam tshuaj lom neeg. Tag nrho oxidized tungsten yog silvery - mov dawb, tab sis nws tseem tuaj yeem tsim cov oxides xws li wo, wo₂, thiab wo₃. Thaum cov concentration ntawm tungsten oxides yog siab, nws cov xim ua tsaus dua. Piv txwv li, wo₂ yog xiav, thiab wo₃ yog daj. Tungsten cov xim kuj tseem cuam tshuam los ntawm nws cov txheej txheem sab hauv thiab kev ua haujlwm sab nraud. Tungsten lub xim kuj tseem tuaj yeem txawv tom qab cua sov lossis nyem.
3. Kev thov ntawm tungsten
Vim nws lub siab melting point, siab ntom, kev coj ua, thiab hluav taws xob tsis kam, thiab thermal yog dav siv nyob rau hauv ntau thaj teb. Piv txwv li, tungsten yog siv nyob rau hauv high - Cov cuab yeej kub xws li tungsten steel, graphite tungsten, tungsten hlau, zog, thiab cov khoom siv mining. Tsis tas li ntawd, Tungerten tseem siv los ua cov khoom hluav taws xob, nqus cov hlab, foob pob hluav taws, alloys, thiab lwm yam.
