Qhov tseem ceeb ntawm tungsten crucibles nyob rau hauv cov txheej txheem kev lag luam tsis tuaj yeem overstated. Lub toughness, siab melting point thiab zoo heev thermal conductivity ntawm tungsten crucibles ua rau lawv indispensable nyob rau hauv tsis tshua muaj lub ntiaj teb smelting, qhov twg huab cua kub yuav tsum tau extract tseem ceeb lub ntiaj teb tsis tshua muaj ntsiab lus. Ib yam li ntawd, tungsten crucibles ua lub luag haujlwm tseem ceeb hauv quartz iav thiab hluav taws xob txau kev lag luam vim tias lawv tuaj yeem tiv taus qhov kub thiab txias ib puag ncig los xyuas kom muaj cov khoom zoo quartz iav thiab cov khoom siv hluav taws xob. Tsis tas li ntawd, nyob rau hauv cov txheej txheem kev loj hlob xws li sapphire ib leeg siv lead ua kev loj hlob, cov yam ntxwv meej thiab txhim khu kev qha ntawm tungsten crucibles yog qhov tseem ceeb rau kev tswj xyuas qhov zoo thiab kev ncaj ncees ntawm cov pob zeb loj hlob, uas cuam tshuam ncaj qha rau kev vam meej thiab tag nrho cov txiaj ntsig ntawm cov txheej txheem kev loj hlob.
