Yuav ua li cas tshem tawm impurities nyob rau hauv silicon carbide cov khoom?: Kev siv cov kua qaub tu txoj kev, kua qaub ntxuav yuav yooj yim heev los ntxuav cov impurities nyob rau hauv silicon carbide, nws txoj kev ua hauj lwm kuj yog heev yooj yim, uas yog, nyob rau hauv cov xwm txheej ntawm cua sov, nrog sulfuric. acid rau silicon carbide rau kev pab tsim nyog, kom sulfuric acid yuav hnov mob nrog hlau hauv silicon carbide, yog li tshem tawm cov impurities. Nyob rau tib lub sijhawm, impurities xws li hlau oxide thiab txhuas kuj yuav hnov mob nrog sulfuric acid, uas tuaj yeem raug tshem tawm zoo. Kuj tseem muaj cov txheej txheem ntawm alkali ntxuav kom tshem tawm, alkali ntxuav txoj kev ntawm silicon carbide yog qhov yooj yim, nws kuj zoo ib yam li cov txheej txheem pickling, uas yog, nyob rau hauv cov xwm txheej ntawm cua sov nrog sodium hydroxide rau silicon carbide kev kho mob, lub ntsiab. Lub hom phiaj yog tshem tawm cov tsos ntawm silicon dawb, silicon dioxide thiab lwm yam, kom cov ntsiab lus ntawm silicon carbide tuaj yeem txhim kho, kom cov ntsiab lus ntawm silicon carbide tuaj yeem nce ntxiv. Yog li ntawd, txoj kev tshem tawm cov impurities hauv silicon carbide cov khoom yog yooj yim heev, nrog rau pickling los yog alkali ntxuav txoj kev yuav ua tau zoo heev kom tshem tawm cov impurities sib txawv, uas yuav ua rau lub purity ntawm silicon carbide cov khoom los txhim kho, thiaj li muaj kev ua tau zoo. , thiab ua qhov tseem ceeb hauv ntau qhov chaw. Yuav ua li cas tshem tawm impurities hauv silicon carbide khoom?
