Whakaahuatanga

Samarium Sm99.9%, 99.99%, ahe hiriwa ma onge te whakarewa whenua, me te hanganga karaihe triclinic, ira whakarewa 1072°C me te kiato 7.54 g/cm³,Ko te hanganga karaihe triclinic, he tino pumau i te hau maroke engari he ngawari ki te waikura i roto i te hau makuku me te whakakotahi ki nga huānga kore konganuku, ka whakarewahia ki te waikawa engari karekau ki te wai.Ka taea te wehea te Samarium mai i etahi atu mea onge whenua ma te tikanga whakawhiti katote, ka rite ranei ma te whakaiti i te waikura samarium ki te barium me te lanthanum.Me pupuri te Samarium i roto i te whare putunga hauhautanga me te maroke, me te matara atu i nga oxidants, waikawa me te makuku etc.He nui te whakamahi a Samarium hei rauemi neutron-absorbing i roto i te umanga ngota ngota, taonga autō pumau, taputapu photoelectric, hanga koranu, ngaruiti me nga taputapu infrared, rauemi taiaho, ka kitea hoki te tono i roto i te waahanga totika me te mara hangarau superconducting kia aukumetia. he ngawari engari he uaua ki te whakaheke, mo nga umanga hiko me te raima.

Tukunga
