Gadolinium

Whakaahuatanga

Gadolinium Gd99.9% 99.99%, he konganuku whenua onge ma te hiriwa me te kaha kaha, te wa tuaono III B huānga roopu me te hanganga karaihe hexagonal, ira whakarewa 1313°C me te kiato 7.901g/m³, ko teautō i te pāmahana rūma me te pūmau i roto i te hau maroke, engari he ngawari ki te waikura me te whakapouri i roto i te hau makuku, karekau ki te wai engari ka memeha ki te waikawa hei hanga i nga tote e rite ana.Ko te konganuku Gadolinium e whakaatu ana i te pai o te kawe, te taima autō teitei me te tohu Curie i te pāmahana rūma, me te mata hopu neutron waiariki teitei.Ko te Gadolinium Gd te nuinga o te wa e whakamahia ana hei neutron te whakauru, te whakahaere me te taonga whakamarumaru i roto i te reactor ngota, a ka whakamahia nuitia hei tapiritanga aukume kowhatu samarium, te hanga puri, nga rauemi aukume-optical, he kaiwhakahaere o te tātaritanga MRI, te reo rekoata aukume whatu, te whakakaha X-ray, i roto i te hangarau ngaruiti, te paura rekoata o te pouaka whakaata tae, me te reo whakamatao autō autō mā te whakamatao aukumetanga kia whiwhi i te pāmahana tino-iti tata ki te kore tino mai i nga tai gadolinium etc.
