Iinkcukacha zeMveliso

Ingcaciso yeMveliso

I-Selenium ibomvu okanye i-gray powder, kunye ne-grey metallic luster quasi - isinyithi.Kwii-allotrophs eziqinileyo ezintandathu ezaziwayo, iikristale ezintathu (α monoitalic, β monoitalic, kunye ne-grey triangulite) zezona zibalulekileyo.Inkqubo yekristale eyi-grey hexagonal yeyona nto izinzile kunye noxinzelelo lwe-4.81g / cm3.

Ikwakho kwiifom ezintathu eziqinileyo ze-amorphous: iifom ezimbini zeglasi ye-selenium, ebomvu kunye nemnyama.Eyangaphambili i-brittle kwaye inobuninzi be-4.26g / cm3.Ubuninzi bokugqibela 4.28g / cm3, enye i-colloidal selenium.
