I-Terbiumingeyesigaba sobunzimaimihlaba engavamile, enensada ephansi kuqweqwe loMhlaba ku-1.1 ppm kuphela. I-Terbium oxide yenza ngaphansi kuka-0.01% wengqikithi yomhlaba eyivelakancane. Ngisho ohlotsheni lwe-yttrium ion oluphezulu olusindayo olungavamile olunokuqukethwe okuphezulu kakhulu kwe-terbium, okuqukethwe kwe-terbium kubala kuphela u-1.1-1.2% wawo wonke umhlaba ongavamile, okubonisa ukuthi uyingxenye yesigaba "esihloniphekile" sezinto zomhlaba ezingavamile. Eminyakeni engaphezu kweyi-100 selokhu kwatholakala i-terbium ngo-1843, ukushoda kwayo nokubaluleka kwayo kuvimbele ukusetshenziswa kwayo okungokoqobo isikhathi eside. Kuseminyakeni engu-30 edlule lapho i-terbium ibonise ithalente layo eliyingqayizivele.
Ukuthola Umlando
Usokhemisi waseSweden uCarl Gustaf Mosander wathola i-terbium ngo-1843. Wathola ukungcola kwayoI-Yttrium(III) oxidefuthiY2O3. I-Yttrium ibizwa ngegama ledolobhana lase-Ytterby eSweden. Ngaphambi kokuvela kobuchwepheshe bokushintshaniswa kwe-ion, i-terbium ayizange ihlukaniswe ngendlela yayo ehlanzekile.
UMosant waqala ukuhlukanisa i-Yttrium(III) oxide yaba izingxenye ezintathu, zonke eziqanjwe ngama-ore: I-Yttrium(III) oxide,I-Erbium(III) oxide, kanye ne-terbium oxide. I-Terbium oxide ekuqaleni yayakhiwe yingxenye ephinki, ngenxa yesici manje eyaziwa ngokuthi i-erbium. “I-Erbium(III) oxide” (kuhlanganise nalokho manje esikubiza ngokuthi i-terbium) ekuqaleni yayiyingxenye engenambala esixazululweni. I-insoluble oxide yalesi sakhi ibhekwa njengensundu.
Kamuva izisebenzi zazingakwazi ukubona i-“Erbium(III) oxide” encane engenambala engenambala, kodwa ingxenye epinki encibilikayo ayinakushaywa indiva. Izimpikiswano mayelana nokuba khona kwe-Erbium(III) oxide ziye zavela ngokuphindaphindiwe. Kulezi zinxushunxushu, igama langempela lashintshwa futhi ukushintshaniswa kwamagama kwakubambekile, ngakho ingxenye ebomvana yagcina ibizwa ngokuthi yisixazululo esiqukethe i-erbium (esixazululweni, yayipinki). Manje kukholakala ukuthi abasebenzi abasebenzisa i-sodium bisulfate noma i-Potassium sulfate bayayithathaI-Cerium(IV) i-oxideiphume ku-Yttrium(III) oxide futhi iguqule i-terbium ngokungenhloso ibe inzika equkethe i-cerium. Cishe u-1% kuphela we-Yttrium(III) oxide yasekuqaleni, manje eyaziwa ngokuthi “terbium”, eyanele ukudlulisa umbala ophuzi ku-Yttrium(III) oxide. Ngakho-ke, i-terbium iyingxenye yesibili eyayiqukethwe ekuqaleni, futhi ilawulwa omakhelwane bayo abaseduze, i-gadolinium ne-dysprosium.
Ngemva kwalokho, noma nini lapho ezinye izakhi zomhlaba ezingavamile zihlukaniswa kule ngxube, kungakhathaliseki ukuthi ingakanani ingxenye ye-oxide, igama le-terbium laligcinwa kuze kube yilapho ekugcineni, i-oxide ensundu ye-terbium yayitholakala isesimweni esihlanzekile. Abacwaningi ekhulwini le-19 abazange basebenzise ubuchwepheshe be-ultraviolet fluorescence ukuze babone amaqhuqhuva aphuzi noma aluhlaza (III), okwenza kube lula ukuthi i-terbium ibonakale ezixubeni eziqinile noma izixazululo.
