Cov kev nplua nuj tsis txaus ntseeg kev tswj hwm kev paub dhau los thiab ib tus neeg rau 1 tus qauv kev pabcuam ua rau qhov tseem ceeb ntawm kev sib txuas lus hauv lub koom haum thiab peb txoj kev nkag siab yooj yim ntawm koj qhov kev cia siab rau Kev Lag Luam Tuam Tshoj Tuam Tshoj Sic Nkoj Nqa Silicon Wafers Rau Qhov Kub Kub Diffusion Txheej Rauv Tube, Peb lub hom phiaj tseem ceeb yog ib txwm muaj. los ua ib lub hom phiaj zoo tshaj plaws thiab tseem ua tus pioneer hauv peb daim teb. Peb paub tseeb tias peb cov kev paub dhau los hauv kev tsim cov cuab yeej yuav tau txais kev ntseeg siab ntawm cov neeg siv khoom, Xav kom koom tes thiab koom ua ke tsim ib lub sijhawm ntev dua nrog koj!
Qhov kev nplua nuj zoo kawg nkaus kev tswj hwm kev paub dhau los thiab ib tus neeg rau 1 tus qauv kev pabcuam ua rau qhov tseem ceeb ntawm kev sib txuas lus hauv lub koom haum thiab peb nkag siab yooj yim ntawm koj cov kev cia siab rauTuam Tshoj nqa Silicon Wafers, Polycrystallie Silicon Wafer, Zoo siab txais tos ib qho ntawm koj cov lus nug thiab kev txhawj xeeb rau peb cov khoom. Peb tos ntsoov yuav tsim kom muaj kev sib raug zoo ua lag luam mus sij hawm ntev nrog koj nyob rau yav tom ntej. Tiv tauj peb hnub no. Peb yog thawj tus neeg koom tes ua lag luam kom haum rau koj cov kev xav tau!
KhoomDsau ntawv
Silicon carbide Wafer Boat yog dav siv los ua tus tuav wafer hauv cov txheej txheem kub diffusion.
Qhov zoo:
Kub kub kuj:ib txwm siv ntawm 1800 ℃
High thermal conductivity:sib npaug rau cov khoom siv graphite
Siab hardness:hardness thib ob tsuas yog pob zeb diamond, boron nitride
Corrosion kuj:muaj zog acid thiab alkali tsis muaj corrosion rau nws, corrosion kuj zoo dua tungsten carbide thiab alumina.
Lub teeb nyhav:tsawg ntom, ze rau aluminium
Tsis muaj deformation: tsawg coefficient ntawm thermal expansion
Thermal shock tsis kam:Nws tuaj yeem tiv taus qhov kub thiab txias hloov, tiv thaiv thermal shock, thiab muaj kev ua haujlwm ruaj khov
