Kev piav qhiantawmBeryllium Flat Khoom
Beryllium yog lub teeb, silver-grey, kuj mos hlau uas muaj zog tab sis nkig.
Beryllium muaj qhov siab tshaj plaws melting point ntawm lub teeb hlau, melting ntawm 1278 degree - considerably siab dua, piv txwv li, lithium (180 degree), sodium (98 degree), magnesium (650 degree), aluminium (660 degree) los yog calcium (839). degree).
Raws li ib txwm muaj, ib txheej nyias ntawm cov tawv oxide BeO cov ntaub ntawv ntawm beryllium nto, tiv thaiv cov hlau los ntawm kev tawm tsam los ntawm dej los yog huab cua. Raws li qhov tshwm sim ntawm BeO txheej no, beryllium tsis oxidize hauv huab cua txawm tias ntawm 600 degree thiab nws tiv thaiv corrosion los ntawm concentrated nitric acid.
Beryllium kuj muaj cov thermal conductivity thiab yog nonmagnetic. Cov tshuaj lom neeg beryllium yog cais raws li alkali ntiaj teb hlau. Beryllium thiab nws cov ntsev yog ob qho tib si lom thiab carcinogenic.
Beryllium yog siv nyob rau hauv kev kho mob kev lag luam rau kev ntsuam xyuas, kev kuaj mob, thiab laser daim ntawv thov vim nws lub zog thiab stability. Nws kuj yog siv rau aerospace thiab tub rog daim ntawv thov vim nws lub teeb yuag zog, tsawg ntom thiab siab thermal conductivity.
