Selenium ili ndi mphuno zinayi: Grey Hexalellic Senium Selenium, buluu pang'ono, ndi ma cmboble a 485 ℃, osungunuka, osungunuka, sungunuka ku sulfuric acid ndi ntloroform; Red Monoclinic Strungstal Selenium, kachulukidwe ka 419g / masentimita, zosungunuka mu madzi, ethanble, zosungunuka mu sulfuric acid ndi nitric acid. Kuchulukitsa kwachibale amorphous Selenium ndi 4.26g / masentimita, komanso kuchuluka kwa kagalasi yagalasi yakuda ndi 4,28g / cm³. Amasinthidwa kukhala hexagonal Selenium pa 180 ℃, ndipo malo owira ndi 685 ℃. Imakhala yopanda mphamvu m'madzi ndipo sungunuka pang'ono mu kaboni.

Selenium ili ndi zojambula ndi zithunzi zaphindu. Magwiridwe antchito a Photoelect amatha kutembenuka kuwala mwachindunji kukhala magetsi, ndipo magwiridwe antchito a zithunzi amatha kuchepetsa kukana powonjezera. Photodelectric ndi zithunzi za Photodelectrits za Selenium zitha kugwiritsidwa ntchito popanga mafilimu ndi mamita owonekera pama matepu ndi maselo a dzuwa. Selenium imatha kusintha zomwe zilipo pakadali pano, motero amagwiritsidwa ntchito kwambiri popanga precesiers. A Selenium Forment ndi semiconductor ya p Mu kujambula, Selenium itha kugwiritsidwa ntchito potengera zikalata ndi zilembo (makatoni a Toner). Mu makampani agalasi, Selenium itha kugwiritsidwa ntchito kupanga galasi lokhala ndi galasi lopata, galasi laziphuphu ndi enamel.
Kalasi
Thandizani Kuchiritsika
Bzalani chomera cha Selenium mutha kuyeretsa ma radicals aulere m'thupi, kuthana ndi mantioxidant, kumalepheretsa kuthamanga kwa lipid peroxide, chotsani cholesterol ya anthu.
Pewani matenda a shuga
Selenium ndiye gawo logwira ntchito ya slutati kuti peroxidase, zomwe zingalepheretse kuchuluka kwa ma cell beta, kuwapangitsa kukhala ndi kagayidwe kambiri, kumalimbikitsa kagayidwe ka magazi, ndikuchepetsa shuga wamagazi, ndikusintha zizindikiro za odwala matenda ashuga.
Pewani kuvuta
Ma retina ali pachiwopsezo chowonongeka chifukwa chowonekera kwambiri ku radiation ya pakompyuta, Selenium imatha kuteteza retina, kuwonjezera pamapeto a thupi la vinayo, kusintha m'maso, ndikupewa ziweto.
