Cov ntaub ntawv tseem ceeb ntawm Tantalum

Tantalum yog cov khoom siv hlau nrog atomic tooj 73 thiab cov cim tshuaj ta. Cov khoom sib xws monomers yog hlau-grey hlau.
Tantalum feem ntau pom nyob rau hauv tantalite, uas yog symbiotic nrog niobium. Tantalum yog ib qho nyuaj, ductile, thiab tuaj yeem kos rau hauv cov ntawv ci. Nws coefficient ntawm thermal expansion yog tsawg heev. Tantalum muaj cov tshuaj zoo heev thiab tiv taus corrosion, ob qho tib si hauv qhov txias thiab kub, thiab tsis hnov ​​​​mob nrog hydrochloric acid, concentrated nitric acid lossis aqua regia. Nws tuaj yeem siv los ua cov hlab ntsha evaporating, thiab lwm yam. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob rau cov raj hluav taws xob, rectifiers thiab electrolytic capacitors. Kev kho mob, nws yog siv los ua nyias nyias los yog cov xov zoo los kho cov ntaub so ntswg puas. Txawm hais tias qhov corrosion kuj ntawm tantalum muaj zog heev, nws cov corrosion kuj yog vim lub cim ntawm ib tug ruaj khov tiv thaiv zaj duab xis ntawm tantalum pentoxide (Ta2O5) nyob rau saum npoo.
