Kev siv cov khoom siv Tantalum: Tantalum machined qhov chaw muaj cov khoom zoo heev xws li lub siab melting point, tsis tshua muaj vapor siab, zoo tswb machining kev ua tau zoo, siab tshuaj stability, siab tsis kam rau cov kua hlau corrosion, thiab siab dielectric tas li ntawm oxide zaj duab xis. Yog li ntawd, tantalum muaj cov ntawv thov tseem ceeb hauv electronics, metallurgy, steel, chemical kev lag luam, cemented carbide, atomic zog, superconducting technology, automotive electronics, scientific research thiab lwm yam high-tech fields.
Tantalum yog cov khoom siv hlau, atomic tooj 73, cov cim tshuaj ta, lub ntsiab lus sib haum rau cov monomers rau cov hlau grey hlau, muaj kev tiv thaiv corrosion siab heev, ob qho tib si hauv qhov txias thiab kub, hydrochloric acid, concentrated nitric acid thiab " aqua regia" tsis muaj zog. Tantalum feem ntau pom nyob rau hauv tantalite, symbiotic nrog niobium. Tantalum lub hardness yog nruab nrab thiab ductile, thiab tuaj yeem kos rau hauv ib qho zoo filament hom nyias nyias. Nws coefficient ntawm thermal expansion yog tsawg heev. Tantalum muaj cov khoom siv tshuaj lom neeg heev thiab tiv taus corrosion heev. Nws tuaj yeem siv los tsim cov hlab ntsha evaporative, thiab lwm yam, tuaj yeem ua rau hauv cov khoom siv hluav taws xob ntawm cov raj hluav taws xob, rectifiers, electrolytic capacitors. Kev kho mob nws yog siv los ua nyias slices los yog nplua hlau los kho cov ntaub so ntswg puas. Txawm hais tias tantalum muaj zog heev rau corrosion, nws cov corrosion kuj yog vim lub cim ntawm ib tug ruaj khov tiv thaiv zaj duab xis ntawm tantalum pentoxide (TaO) nyob rau saum npoo.
