Chemical Properties ntawm Tantalum

Tantalum muaj cov tshuaj zoo heev thiab tiv taus corrosion, ob qho tib si hauv qhov txias thiab kub, thiab tsis hnov ​​​​mob rau hydrochloric acid, concentrated nitric acid lossis "aqua regia". Txawm li cas los xij, Tantalum tuaj yeem corroded hauv kub concentrated sulfuric acid. Hauv qab 150 degrees Celsius, Tantalum yuav tsis raug corroded los ntawm concentrated sulfuric acid, thiab tsuas yog reacts ntawm kub siab tshaj qhov no.

Nyob rau hauv 175 degrees ntawm concentrated sulfuric acid rau 1 xyoo, lub thickness ntawm corroded 0. tsuas yog puas 0.006 hli. Ntawm 250 degrees, tus nqi corrosion tau nce, rau txhua xyoo yog corroded thickness ntawm 0.116 hli.

Ntawm 300 degrees, tus nqi ntawm corrosion yog ceev dua, raus nyob rau hauv 1 xyoo, qhov nto yog corroded 1.368 hli. Nyob rau hauv fuming sulfuric acid corrosion tus nqi yog loj tshaj nyob rau hauv concentrated sulfuric acid, nyob rau hauv 130 degrees ntawm kev daws rau immersed nyob rau hauv 1 xyoo, qhov nto yog corroded thickness ntawm 15.6 hli.
