Iridium Crucible Description
SSC tshwj xeeb hauv kev muab iridium crucibles nrog ntau qhov ntev xws li cylindrical thiab conical nyob rau hauv ntau txoj kab uas hla thiab phab ntsa thicknesses.
Iridium crucibles feem ntau yog siv rau hauv ib txoj kev loj hlob siv lead ua, uas yog Czochralski method (CZ method). Nyob rau hauv cov txheej txheem no, noob muaju yog qhia rau melted raw cov ntaub ntawv nyob rau hauv lub crucible. Cov sib tov yog ces tig thiab rub tawm maj mam. Cov khoom siv lead ua siv cov qauv no suav nrog cov lithium tantalite crystals rau cov suab nrov lim hauv xov tooj ntawm tes thiab sapphire crystals rau LED substrate.
Iridium muaj qhov kub siab heev ntawm 2,400 degree. Nws kuj yog heev resistant rau corrosion. Ob tus yam ntxwv no ua rau Iridium crucibles zoo tagnrho rau kev loj hlob siv lead ua.
