Rare Earth element |Samarium(Sm)
Muna 1879, Boysbaudley akawana chinhu chitsva chisingawanzoitiki chepasi mu "praseodymium neodymium" yakawanikwa kubva niobium yttrium ore, ndokuitumidza samarium maererano nezita reiyi ore.
Samarium iruvara rweyero uye ndiyo mbishi yekugadzira Samarium cobalt yakavakirwa magineti asingagumi. Samarium cobalt magineti aive magineti ekutanga asingawanzo kushandiswa muindasitiri. Iri rudzi rwechigarire magineti rine marudzi maviri: SmCo5 akatevedzana uye Sm2Co17 akatevedzana. Mukutanga kwema1970, iyo SmCo5 yakatevedzana yakagadzirwa, uye munguva yakazotevera, iyo Sm2Co17 yakatevedzana yakagadzirwa. Ikozvino ndiko kudiwa kwekupedzisira ndiko kunonyanya kutariswa. Kuchena kwesamarium oxide inoshandiswa musamarium cobalt magineti haidi kunge yakakwira zvakanyanya. Kubva pakuona mari, inenge 95% yechigadzirwa inonyanya kushandiswa. Mukuwedzera, samarium oxide inoshandiswawo mu ceramic capacitors uye catalysts. Pamusoro pezvo, samarium zvakare ine zvivakwa zvenyukireya, izvo zvinogona kushandiswa sezvimiro zvekugadzira, zvidziviriro zvekudzivirira uye zvigadziriso zveatomu simba reactor, zvichiita kuti nyukireya fission ibudise simba rakakura kuti rishandiswe zvakachengeteka.
