High Temperature Performance ntawm Silicon Carbide Crucibles

Silicon carbide cruciblespaub txog lawv cov kev ua haujlwm kub zoo heev thiab muaj peev xwm tiv taus kev ua haujlwm siab heev. Feem ntau, cov khoom siv zoo silicon carbide crucibles tuaj yeem ua haujlwm zoo thiab ruaj khov hauv qhov kub ntawm 1600 ° C txog 2200 ° C (2912 ° F txog 3992 ° F), thiab qee qhov tshwj xeeb tsim thiab kho crucibles tuaj yeem tiv taus kub txog 2700 ° C. C (4952 ° F).

Nyob rau hauv cov ntaub ntawv siv nyob rau hauv high-temperature thwmsim los yog ntau lawm txheej txheem xws li hlau smelting thiab ceramic sintering, qhov tshwj xeeb ua hauj lwm kub ntawm silicon carbide crucible yuav tsum tau txiav txim raws li cov txheej txheem tshwj xeeb, atmospheric tej yam kev mob thiab cov tshuaj lom neeg cov khoom ntawm cov khoom. Tsis tas li ntawd, cov txheej txheem ua haujlwm kom raug yuav tsum tau ua raws li txhawm rau tiv thaiv lub crucible los ntawm kev tawg lossis puas vim qhov kub thiab txias hloov sai.

Txawm hais tias silicon carbide crucibles tuaj yeem tiv taus qhov kub thiab txias, nws yog ib qho tseem ceeb kom tsis txhob siab tshaj lawv qhov siab tshaj plaws kev khiav hauj lwm kub los tiv thaiv kev puas tsuaj rau cov khoom los yog cov tsos ntawm impurities. Cov txheej txheem ua kom txias kom zoo yuav tsum tau ua raws li tom qab siv los tiv thaiv kev tawg thaum muab tso rau ntawm qhov chaw txias dua, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev cuam tshuam lub cev ntau dhau thaum siv los tiv thaiv kev puas tsuaj.
