Incazelo Yomkhiqizo

I-Selenium iyimpushana ebomvu noma empunga, ene-grey metallic luster quasi - insimbi.Kuma-allotroph aqinile ayisithupha aziwayo, amakristalu amathathu (α monoitalic, β monoitalic, kanye ne-grey triangulite) abaluleke kakhulu.Isistimu yekristalu eyi-hexagonal empunga iyona ezinze kakhulu enobukhulu obungu-4.81g/cm3.

Ikhona futhi ngezinhlobo ezintathu eziqinile ze-amorphous: izinhlobo ezimbili zengilazi ze-amorphous ze-selenium, ezibomvu nezimnyama.Eyangaphambili i-brittle futhi inokuminyana okungu-4.26g/cm3.Ukuminyana kokugcina 4.28g/cm3, enye i-colloidal selenium.
