Tantalum (Ta) General Information:

Tantalum tshuaj cim Ta, steel grey hlau, VB tsev neeg nyob rau hauv lub sij hawm lub rooj, atomic tooj 73, atomic hnyav 180. 9479, lub cev-centered cubic siv lead ua, common valence yog + 5. Tantalum yog tsawg hardness thiab oxygen cov ntsiab lus-dependent, zoo tib yam ntshiab. tantalum, annealed Vickers hardness tsuas yog 140 hv. Nws cov ntsiab lus melting yog siab li 2995 ° C, qeb thib tsib ntawm cov khoom yooj yim, tom qab carbon, tungsten, rhenium thiab osmium. Tantalum yog qhov yooj yim heev thiab tuaj yeem kos rau hauv cov ntaub ntawv nyias nyias. Nws yog me me Coefficient ntawm thermal expansion. Nws tsuas yog nthuav tawm los ntawm 6.6 qhov chaw hauv ib lab ib degree Celsius. Tsis tas li ntawd, nws qhov toughness yog qhov muaj zog heev, txawm tias zoo dua li tooj liab.

Tantalum feem ntau pom nyob rau hauv tantalite thiab coexists nrog niobium. Tantalum muaj nruab nrab hardness thiab zoo ductility, thiab tuaj yeem kos rau hauv cov ntawv ci nyias ntawm cov hlau zoo. Nws yog me me Coefficient ntawm thermal expansion. Tantalum yog cov cuab yeej tshuaj lom neeg thiab muaj zog tiv taus corrosion. Nws tsis hnov ​​​​mob nrog hydrochloric acid, concentrated nitric acid lossis aqua regia hauv ob qho tib si kub thiab txias. Nws tuaj yeem siv los ua evaporator thiab lwm yam. Nws kuj tseem siv tau ua electrode ntawm electron tube, rectifier thiab electrolytic capacitor. Siv kev kho mob los ua cov ntawv los yog xov los xaws cov ntaub so ntswg puas. Txawm hais tias tantalum muaj zog heev rau corrosion, nws tsis kam mus rau corrosion yog vim tsim ib tug ruaj khov tantalum pentoxide (TA205) tiv thaiv zaj duab xis ntawm nws nto.


Tantalum muaj ntau yam kev siv vim nws cov khoom tshwj xeeb. 

Tantalum tuaj yeem siv los hloov cov hlau tsis huv hauv kev tsim ntau yam inorganic acids. 

Tsis tas li ntawd, nyob rau hauv cov tshuaj, hluav taws xob, hluav taws xob thiab lwm yam lag luam, 

tantalum tuaj yeem hloov qhov kev xav tau yav dhau los los ua haujlwm ntawm cov hlau zoo nkauj platinum, 

Tantalum yog tsim los ua lub capacitor siv rau hauv cov khoom siv tub rog. 

Ib nrab ntawm lub ntiaj teb no tantalum ntau lawm yog siv nyob rau hauv zus tau tej cov tantalum capacitors.


Tantalum (Ta) Hlau Element Txheej txheem cej luam:

Peb smelts ib yam ntawm cov hlau thiab feem ntau lwm cov ntaub ntawv siab heev rau hauv pas nrig, bar los yog phaj daim ntawv, los yog cov neeg muas zaub muab cov khoom kos duab.

Peb muag cov khoom sib txawv ntawm cov khoom siv hlau los ntawm cov khoom hnyav los yog cov khoom siv sib txawv hauv cheeb tsam tshawb fawb thiab rau cov cuab yeej tshiab.


Piv txwv li: Tantalum sputtering phiaj, tantalum pellets, alloy tantalum, tantalum phaj, tantalum ntawv, tantalum ingot, tantalum pob, tantalum raj, tantalum yeeb nkab, tantalum ntawv ci. 

Lwm cov duab muaj nyob ntawm kev thov.
