Tantalum yog cov khoom siv tshuaj nrog lub cim Ta thiab tus lej atomic 73. Nws yog tsim los ntawm tantalum atoms nrog 73 protons hauv lub nucleus. Tantalum yog ib qho tsis tshua muaj, tawv, xiav-grey, lustrous hloov pauv hlau uas muaj zog tiv taus corrosion. Nws yog feem ntau alloyed nrog lwm cov hlau los txhim kho nws cov khoom siv kho tshuab thiab siv ntau yam kev siv, suav nrog hluav taws xob, aerospace thiab cov cuab yeej kho mob.

Tantalum muaj ntau yam tshuaj muaj txiaj ntsig zoo:

1. Corrosion tsis kam: Tantalum yog corrosion-resistant, ua rau nws haum rau siv nyob rau hauv corrosive ib puag ncig xws li tshuaj ua thiab kev kho mob cog.

2. High melting point: Tantalum muaj qhov kub siab heev melting point, tshaj 3000 degrees Celsius, uas ua rau nws muaj txiaj ntsig zoo rau kev siv kub.

3. Inertness: Tantalum kuj yog inert, uas txhais tau hais tias nws tsis yooj yim react nrog lwm yam ntsiab lus los yog tebchaw nyob rau hauv ib txwm tej yam kev mob.

4. Oxidation tsis kam: Tantalum tsim cov txheej txheem oxide tiv thaiv thaum raug huab cua, ntxiv rau kev tiv thaiv corrosion.

Cov khoom no ua rau tantalum muaj txiaj ntsig hauv ntau yam kev lag luam thiab kev siv.

Tantalum yog tsim los ntawm ntau yam txheej txheem geological. Nws yog feem ntau pom nrog rau lwm yam minerals, xws li columbite-tantalite (coltan), thiab feem ntau yog muab rho tawm raws li ib tug by-product ntawm mining ntawm lwm yam hlau, xws li tin. Tantalum muaj nyob rau hauv pegmatites, uas yog coarse-grained igneous pob zeb uas feem ntau muaj siab concentrations ntawm tsis tshua muaj ntsiab.

Kev tsim ntawm tantalum deposits koom nrog lub crystallization thiab txias ntawm lava thiab cov tom ntej concentration ntawm tantalum-muaj minerals los ntawm cov txheej txheem geological xws li hydrothermal kev ua si thiab huab cua. Nyob rau tib lub sijhawm, cov txheej txheem no tsim tantalum-nplua nuj ores uas tuaj yeem raug mined thiab ua tiav kom rho tawm tantalum rau ntau yam kev lag luam thiab kev siv.

Tantalum tsis yog nyob rau hauv magnetic. Nws raug suav hais tias yog non-magnetic thiab muaj qhov sib nqus permeability tsawg. Cov cuab yeej no ua rau tantalum muaj txiaj ntsig hauv cov ntawv thov uas yuav tsum muaj tus cwj pwm tsis sib nqus, xws li hauv cov khoom siv hluav taws xob thiab cov khoom siv kho mob.
