Dab tsi yog qhov kev sib tw loj hauv Niobium raj tsim khoom?
Kev tsim cov khoom ntawm niobium tubes pib ntau cov kev sib tw vim nws lub siab melting point (2,468 degree) thiab brittleeness ntawm chav sov.
Cov txheej txheem tshwj xeeb xws li hluav taws xob nqaj vuam, lub tshuab nqus tsev ARC rov qab (var) thiab extrusion nyob rau hauv cov huab cua tsis zoo yuav tsum tau zam kev tsis xws luag .
Nws kuj tseem yog qhov tseem ceeb los tswj cov kev huv ntawm niobium (feem ntau yog tshaj 99 .}} Cov nqi tsim tawm tau ntau dua li ntawm cov hlau zoo nkauj.
