Mafotokozedwe Akatundu

Selenium ndi ufa wofiira kapena wotuwa, wokhala ndi chitsulo chonyezimira chonyezimira - chitsulo.Pa ma allotrophs olimba asanu ndi limodzi odziwika, makhiristo atatu (α monoitalic, β monoitalic, ndi grey triangulite) ndi ofunika kwambiri.Dongosolo lotuwa la hexagonal crystal system ndiyokhazikika kwambiri yokhala ndi kachulukidwe ka 4.81g/cm3.

Imapezekanso mumitundu itatu yolimba ya amorphous: magalasi awiri amorphous a selenium, ofiira ndi akuda.Yoyamba ndi yolimba ndipo imakhala ndi makulidwe a 4.26g/cm3.Kachulukidwe kotsiriza 4.28g/cm3, ina ndi colloidal selenium.
