Selenium ifite allomorphs enye: gray hexagonal metallic selegic, ubururu buke, hamwe nubucucike bwa 685. Umutuku Monoclinic Crystal Selenimic, ubucucike bugereranije ni 4.39g / CM³, Gushonga Ingingo ya 685 ℃, guswera mu mazi, ubudake muri acide sulfuric na acide ya nitric; Ubusa bugereranije Selenuim itukura ni 4.26G / CM³, hamwe nuburwayi bugereranije Selegiy Gelacey Selenium ni 4.28G / CM³. Yahinduwe muri Selegiyone Selegium ya Hexonium kuri 180 ℃, hamwe ningingo zibi ni 685 ℃. Ntabwo yashonga mumazi no gushonga gato muri karubone depulfide.

Imikoreshereze y'ibicuruzwa
Gukoresha inganda
Selenium ifite imiterere ya fotoectic hamwe numutungo wamafoto. Imikorere ya Phofeterictric irashobora guhindura urumuri mu mashanyarazi, kandi imikorere yimikorere irashobora kugabanya kurwanya mugihe wiyongera. Umutungo wa Phosefectike na Photofectique wa Selenimine urashobora gukoreshwa mugukora amafoto hamwe na metero zigaragara kuri kamera nimirasire yizuba. Selenium irashobora guhindura ubundi buryo muri iki gihe, bityo birakoreshwa cyane mu gukora ibishushanyo mbonera. Selenium elemental ni ubwoko bwa p-ubwoko bushobora gukoreshwa mumirongo yumuzunguruko nibigize leta. Muri fotokopi, Selenium irashobora gukoreshwa mugukoporora ibyangombwa ninyuguti (amakarito ya toner). Mu nganda yikirahure, Selenium irashobora gukoreshwa mugukora ikirahure cya decolorize, ruby yirahuri na enamel.
Icyiciro cya Meidical
Kuzamura ubudahangarwa
Tera Imbere Selegium irashobora gukuraho imirasire yubusa mumubiri, ikuraho toxine mumubiri, antioxidant, ibuza gukora ibintu bya lipid, irinda impinja za lipdide, irinde imikorere yamaraso, kandi ukureho filire idakingiwe.
Irinde diyabete
Selenium nibigize glutathione peroxidase, bishobora kubuza kurimbuka kwa okiside, bigatuma bakora metabolism ya beta, bigateza imbere isukari isukari, bigabanya isukari yisukari, no kunoza ibimenyetso byamava.
Irinde cataract
Retina yibasiwe no kwangirika kubera guhura n'imirasire ya mudasobwa, Seleniyi irashobora kurinda retina, kuzamura iherezo ryumubiri wa vit, no gukumira amaso.
