Txog Tungsten Hlau
Tungsten yog ib hom hlau. Nws lub cim qhia yog "W"; Nws tus lej atomic yog 74 thiab nws qhov hnyav atomic yog 183.84. Nws yog dawb, tawv heev thiab hnyav. Nws yog ib feem ntawm tsev neeg chromium thiab muaj cov khoom siv tshuaj ruaj khov. Nws lub cev siv lead ua lub cev-centered cubic siv lead ua qauv (BCC). Nws lub ntsiab lus yaj yog nyob ib puag ncig 3400 ℃ thiab nws lub ntsiab lus kub yog tshaj 5000 ℃. Nws qhov hnyav sib piv yog 19.3. Nws yog ib hom hlau tsis tshua muaj.
