Ukufumana iMbali

Usokhemisti waseSweden uCarl Gustaf Mosander wafumanisa i-terbium ngo-1843. Wafumanisa ukungcola kwayoi-yttrium oxidekwayeY2O3. Yttriumithiywe ngelali yase-Itby eSweden. Ngaphambi kokuvela kweteknoloji yokutshintshiselana kwe-ion, i-terbium ayizange yodwa ngendlela ecocekileyo.

UMossander waqala wahlulahlulai-yttrium oxidezibe ziinxalenye ezintathu, zonke zithiywe ngegama lentsimbi:i-yttrium oxide, i-erbium oxide, kwayei-terbium oxide. I-Terbium oxideyayilwa kuqala ngendawo epinki, ngenxa yento eyaziwa ngokuba yiierbium. I-Erbium oxide(kuquka le nto ngoku siyibiza ngokuba yi-terbium) ekuqaleni yayiyinxalenye engenambala kwisisombululo. I-oxide enganyibilikiyo yale elementi ithathwa ngokuba mdaka.

Kamva abasebenzi bakufumanisa kunzima ukubona into encinane engenambala “i-erbium oxide", kodwa inxalenye epinki enyibilikayo ayinakuhoywa. Ingxoxo malunga nobukho bei-erbium oxideiye yavela ngokuphindaphindiweyo. Kwisiphithiphithi, igama lokuqala latshintshwa kwaye ukutshintshiselwa kwamagama kwagxininiswa, ngoko inxalenye yepinki ekugqibeleni yachazwa njengesisombululo esiqulethe i-erbium (kwisisombululo, yayiyipinki). Ngoku kukholelwa ukuba abasebenzi abasebenzisa i-sodium disulfide okanye i-potassium sulfate ukususa i-cerium dioxidei-yttrium oxideujike ungaqondangaterbiumkwi-cerium equlethe imvula. Ngoku eyaziwa ngokuba 'terbium', kuphela malunga ne-1% yoqoboi-yttrium oxideikhona, kodwa oku kwanele ukuthumela umbala omthubi okhanyayoi-yttrium oxide. Ngoko ke,terbiumyinxalenye yesibini ebinayo ekuqaleni, kwaye ilawulwa ngabamelwane bayo abasondeleyo,gadoliniumkwayeidysprosium.

Emva koko, nanini na enyeumhlaba onqabileyoizinto zahlulwa kulo mxube, nokuba ungakanani na umlinganiselo we oxide, igama le terbium lagcinwa de ekugqibeleni, i<em>brown oxideterbiumyafunyanwa ikwimo ecocekileyo.
