Physical And Chemical Properties Of Tantalum

Tantalum (Tantalum) tshuaj cim yog "Ta", atomic tooj yog 73, atomic hnyav yog 180.9479, belongs rau lub sij hawm system, chav kawm ntawv V, sub-group (vanadium) ntsiab. Nws yog ib tug silver-dawb hlau nrog ib tug loj valence ntawm +5 thiab zoo corrosion kuj. Hauv 200 degree hauv qab no, tsuas yog nrog fluorine, hydrofluoric acid, muaj zog alkali tov, fuming sulfuric acid ua. Nyob rau hauv chav tsev kub, nws tsis cuam tshuam los ntawm hydrochloric acid, nitric acid thiab sulfuric acid, tsis ua nrog aqua regia, thiab muaj kev ruaj ntseg zoo rau cov kua qaub.

Tantalum yog malleable, tuaj yeem kos rau hauv cov hlau zoo nkauj nyias nyias. Nws coefficient ntawm thermal expansion yog tsawg heev, txhua txhua 1 degree tsuas yog 0.00066% expansion. Tsis tas li ntawd, nws toughness yog heev muaj zog thiab superior rau cov tooj liab.
Tantalum plays lub luag haujlwm tseem ceeb hauv kev phais thiab tshuaj, tsis yog rau kev tsim khoom siv kho mob nkaus xwb, tab sis kuj yog ib qho zoo heev "cov khoom siv bio-adaptive". Piv txwv li, Tantalum nplooj tuaj yeem siv los them nyiaj rau kev puas tsuaj rau pob txha taub hau, Tantalum hlau tuaj yeem siv los kho cov hlab ntsha thiab cov leeg, Tantalum strips tuaj yeem siv los hloov cov pob txha tawg thiab pob qij txha, thiab Tantalum yarn lossis mesh ua los ntawm Tantalum hlau tuaj yeem ua tau. siv los them nyiaj rau cov leeg nqaij.
