Isingeniso esifushane se-tantalum metal element

intengo yensimbi ye-tungsten

I-Tantalum (i-Tantalum) iyingxenye yensimbi enenombolo ye-athomu engu-73, a

uphawu lwamakhemikhali u-Ta, indawo yokuncibilika engu-2996 °C, iphoyinti elibilayo elingu-5425 °C,

kanye nokuminyana okungu-16.6 g/cm³. I-elementi ehambisana ne-elementi ithi

insimbi empunga, enokumelana nokugqwala okuphezulu kakhulu. Ayikwenzi

isabela ku-hydrochloric acid, i-nitric acid egxilile kanye ne-aqua regia kungakhathaliseki ukuthi yikuphi

ngaphansi kwezimo ezibandayo noma ezishisayo.

I-Tantalum ikakhulukazi ikhona ku-tantalite futhi ihlangana ne-niobium. I-Tantalum

iqine ngokulingene futhi idubule, futhi ingadonswa ibe imicu emincane ukuze yenziwe

ama-foil amancane. I-coefficient yayo yokwandisa okushisayo incane. UTantalum unamandla kakhulu

izakhiwo zamakhemikhali ezinhle futhi amelana kakhulu nokugqwala. Kungaba njalo

esetshenziselwa ukwenza imikhumbi yokuhwamuka, njll., futhi ingasetshenziswa njengama-electrode,

ama-rectifiers, nama-electrolytic capacitor amashubhu e-electron. Kwezokwelapha, isetshenziswa

yenza amashidi amancane noma izintambo zokulungisa izicubu ezilimele. Nakuba i-tantalum

imelana kakhulu nokugqwala, ukumelana kwayo nokugqwala kungenxa yokwakheka

yefilimu evikelayo ezinzile ye-tantalum pentoxide (Ta2O5) ngaphezulu.
