Nrog rau kev tsim cov khoom siv SiC uas muaj cov khoom siv hluav taws xob maj mam zuj zus, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ruaj khov thiab rov ua dua ntawm cov txheej txheem. Tshwj xeeb, kev tswj hwm cov qhov tsis zoo, kev hloov kho me me lossis kev hloov pauv ntawm lub tshav kub hauv lub cub tawg, yuav ua rau muaj kev hloov pauv siv lead ua lossis kev nce ntxiv ntawm cov qhov tsis zoo. Hauv lub sijhawm tom qab, peb yuav tsum ntsib qhov kev sib tw ntawm "loj hlob sai, ntev thiab tuab, thiab loj hlob", ntxiv rau kev txhim kho ntawm kev tshawb fawb thiab kev tsim kho, peb kuj xav tau cov ntaub ntawv thermal teb siab dua los ua kev txhawb nqa. Siv cov ntaub ntawv siab heev, cog cov siv lead ua siab heev.
Kev siv cov khoom siv crucible tsis raug, xws li graphite, porous graphite, tantalum carbide hmoov, thiab lwm yam hauv qhov chaw kub yuav ua rau muaj qhov tsis zoo xws li muaj cov pa roj carbon ntau ntxiv. Tsis tas li ntawd, hauv qee qhov kev siv, qhov permeability ntawm porous graphite tsis txaus, thiab xav tau cov qhov ntxiv kom ua rau permeability ntau ntxiv. Cov porous graphite nrog permeability siab ntsib cov teeb meem ntawm kev ua, kev tshem tawm hmoov, etching thiab lwm yam.
VET qhia txog tiam tshiab ntawm SiC siv lead ua kom loj hlob thermal field khoom siv, porous tantalum carbide. Kev tshwm sim thoob ntiaj teb.
Lub zog thiab qhov nyuaj ntawm tantalum carbide yog siab heev, thiab ua rau nws muaj qhov porous yog qhov nyuaj. Kev ua cov tantalum carbide porous nrog porosity loj thiab purity siab yog qhov nyuaj heev. Hengpu Technology tau tshaj tawm qhov kev tshawb pom porous tantalum carbide nrog porosity loj, nrog qhov siab tshaj plaws porosity ntawm 75%, ua tus thawj coj thoob ntiaj teb.
Siv tau cov khoom siv lim dej los ntawm cov pa roj, hloov qhov kub thiab txias hauv zos, kev coj ntawm cov khoom ntws, tswj kev xau, thiab lwm yam. Nws siv tau nrog lwm cov khoom tantalum carbide (compact) lossis tantalum carbide txheej los ntawm Hengpu Technology los tsim cov khoom hauv zos nrog cov dej ntws sib txawv.
Qee cov khoom siv tau rov siv dua.
