Pure Gallium Hlau
Lub melting point ntawm gallium yog tsawg heev, tab sis lub boiling point yog siab heev. Cov kua dej ntshiab ntshiab muaj qhov tseem ceeb rau kev txias txias thiab yooj yim oxidized hauv huab cua los tsim cov oxide zaj duab xis.

Lub melting point ntawm gallium yog tsawg heev, tab sis lub boiling point yog siab heev. Cov kua dej ntshiab ntshiab muaj qhov tseem ceeb rau kev txias txias thiab yooj yim oxidized hauv huab cua los tsim cov oxide zaj duab xis.
Lub teeb xiav hlau, nws dhau los ua cov kua dej dawb ntawm 29.76 degree. Kua gallium yog yooj yim supercooled, uas yog, nws yog txias rau 0 degree yam tsis muaj solidification. Me ntsis soluble hauv mercury, tsim gallium amalgam. Gallium tuaj yeem nkag mus rau iav, yog li nws tsis haum rau khaws cia hauv cov iav ntim.
Thaum rhuab mus rau lub melting point, nws ua kua, thiab ces txias mus rau 0 degree yam tsis muaj solidification. Thaum nws hloov los ntawm cov kua rau cov khoom, nws cov ntim nce li ntawm 3.2 feem pua. Lub hardness yog 1.5 txo 2.5. Gallium ruaj khov hauv huab cua qhuav ntawm chav tsev kub.
