- Kev siv cov khoom pov tseg tungsten rov ua dua tshiab, nws paub zoo tias tungsten yog ib hom hlau tsis tshua muaj, cov hlau tsis tshua muaj yog cov peev txheej tseem ceeb, thiabtungstenmuaj daim ntawv thov tseem ceeb heev.
- Nws yog ib feem tseem ceeb ntawm cov khoom siv tshiab niaj hnub no, cov khoom siv hluav taws xob kho qhov muag, cov hlau tshwj xeeb, cov khoom siv ua haujlwm tshiab thiab cov hlau sib xyaw, thiab lwm yam. Txhua tus yuav tsum siv cov khoom tshwj xeeb ntawmtungsten. Xwmphooj ywg, tungstenpov tseg cov khoom siv theem ob no, nws cov khoom siv rov ua dua tshiab muaj nqis heev rau kev lag luam.Tungstencov khib nyiab feem ntau muaj ob pawg: ib hom yogtungstenthiabtungstencov khoom siv ua cov khoom siv hlau, xws li cov khoom siv sintering kawg ntawm tus pas nrig (lub taub hau),tungsten carbidechaw ua haujlwm pov tseg, sib tsoo carbide slag thiab hlau oxide txheej thiab txiav daim, thiab lwm yam. Lwm hom yog hnav, hnav tawm lossis tso tseg uas muaj cov ntaub ntawv tungsten, xws li cov cuab yeej txiav tungsten carbide pov tseg thiab cov catalyst siv.
