Txheej txheem cej luam ntawm Tantalum

Tantalum, raws li ib txwm refractory hlau, tsis tsuas yog ruaj khov nyob rau hauv nws cov tshuaj, tab sis kuj muaj biocompatibility zoo nrog tib neeg cov ntaub so ntswg. Tantalum hlau tsis ua rau tib neeg cov leeg nqaij ib leeg, thiab tsis cuam tshuam rau tib neeg cov leeg nqaij, yog li ntawd, tantalum hlau tau lees paub los ntawm cov neeg kho mob tau lees paub tias yog qhov zoo tshaj plaws biocompatible tawv nqaij cog khoom, uas tau siv rau hauv kev kho mob rau ntau xyoo. Nrog rau kev txhim kho ntawm kev kho mob qib thiab cov khoom siv science, qhov kev thov kho mob rau kev kho mob tantalum hlau cog kuj tau ua tus kheej. Hmoov txaj 3D tshuab luam ntawv yog ib qho zoo txhais tau tias kom ua tiav cov kev npaj ntawm cov cog cog thiab tau ua tiav zoo hauv kev npaj cov titanium cog. Txawm li cas los xij, tantalum xav tau lub siab melting point ntawm 2996 degree, uas yog 1.8 npaug siab dua li ntawm titanium (1668 degree); zoo thermal conductivity, nrog ib tug thermal conductivity [57.5 W / (mK)] uas yog 3.8 lub sij hawm siab tshaj ntawm titanium, uas ua rau muaj kev sib tw rau kev xaiv cov hmoov raw cov ntaub ntawv thiab kev tswj ntawm molding tsis, thiab yog li cov uas twb muaj lawm 3D luam ntawv. ntawm metallic tantalum tseem nyob rau theem kev tshawb fawb.
