Cov khoom ntawm Tantalum

Tantalum muaj qhov melting point ntawm 2980 degree thiab yog thib peb feem ntau refractory hlau tom qab tungsten thiab rhenium. Ntshiab tantalum me ntsis xiav xim, zoo heev plasticity, nyob rau hauv lub txias lub xeev yam tsis muaj annealing nruab nrab yuav dov rau hauv nyias nyias (tsawg tshaj 0.01 hli) phaj.

Tantalum melting point, boiling point yog siab, tab sis lub electron khiav khiav hauj lwm tshaj tungsten, molybdenum thiab lwm yam refractory hlau rau qhov tsawg, vim tsis muaj zog emit electrons, tau siv nyob rau hauv lub tshuab nqus tsev vacuum technology.

Tantalum corrosion kuj zoo ib yam li iav, ntawm qhov kub nruab nrab (txog 150 degree) tsuas yog fluorine, hydrofluoric acid, sulfur trioxide (xws li fuming sulfuric acid), muaj zog alkali thiab qee cov ntsev ntsev ntawm tantalum muaj kev cuam tshuam. Tantalum hlau ruaj khov nyob rau hauv huab cua ntawm chav tsev kub, thiab ceev oxidation kom tsim Ta205 thaum rhuab mus rau siab tshaj 500 degree.
