Terbium yog siv Raws li ib tug dopant nyob rau hauv calcium fluoride, calcium tungstate, thiab strontium molybdate, cov ntaub ntawv uas yog siv nyob rau hauv cov khoom siv hauv lub xeev, thiab raws li cov siv lead ua stabilizer ntawm cov roj hlwb uas ua haujlwm ntawm qhov kub siab, ua ke nrog ZrO2. Terbium kuj yog siv nyob rau hauv alloys thiab nyob rau hauv zus tau tej cov khoom siv hluav taws xob.

Ntawm no, terbium nyob qhov twg hauv ntiaj teb?

Tsis yog pom nyob rau hauv cov xwm li dawb keeb, tab sis yog muaj nyob rau hauv ntau yam minerals. Cov ore tseem ceeb tshaj plaws yog monazite, bastnasite thiab cerite. Cov chaw mining tseem ceeb yog Tuam Tshoj, Tebchaws Asmeskas, Is Nrias teb, Sri Lanka, Brazil thiab Australia thiab reserves fo terbium kwv yees li ntawm 300,000 tonnes.

Ib yam li ntawd, tib neeg nug, puas yog Terbium siv hauv xov tooj ntawm tes?

Zoo li cov khoom, Minerals, thiab qee yam khoom siv. Terbium dua yog ib qho ntawm ntau cov ntsiab lus hauv lub xov tooj (Nws lub cim yog "Tb"). Terbium yog siv nyob rau hauv Circuit Court boards thauj lub zog. Kub yog ib yam khoom thiab cov ntxhia hauv koj xov tooj.

Puas yog tib neeg lub cev siv terbium?

17 radioactive isotopes ntawm terbium nqa cov lej ntawm 147 txog 158 thiab 160 txog 164. Ib qho hluav taws xob isotope, terbium -149, ib siv hauv tshuaj. Cov isotope yog txhaj ncaj qha rau hauv cov qog nqaij hlav cancer hauv tus neeg mob lub cev.
