Cov txheej txheem tsim khoom ntawmdub silicon carbidefeem ntau muaj cov kauj ruam nram qab no:
1. Kev Npaj Khoom Siv Raw: Cov khoom siv tseem ceeb rau kev tsim cov silicon carbide dub yog cov xuab zeb silica zoo thiab roj av coke. Cov ntaub ntawv no raug xaiv thiab npaj ua tib zoo rau kev ua tiav ntxiv.
2. Kev Sib Tov: Cov xuab zeb silica thiab roj av coke raug sib xyaw ua ke raws li qhov xav tau kom ua tiav cov tshuaj lom neeg xav tau. Lwm cov khoom ntxiv kuj tseem yuav raug ntxiv rau theem no los txhim kho cov khoom tshwj xeeb ntawm cov khoom kawg.
3. Kev Sib Tsoo thiab Kev Sib Tsoo: Cov khoom siv raw sib xyaw ua ke raug sib tsoo thiab sib tsoo ua hmoov zoo. Cov txheej txheem no pab ua kom tau txais qhov sib npaug ntawm cov khoom me me, uas yog qhov tseem ceeb rau kev tau txais cov khoom zoo sib xws.
4. Kev Ua Carbonization: Cov hmoov sib tov ces muab tso rau hauv lub cub tawg hluav taws xob lossis lub cub tawg graphite. Qhov kub tau nce mus txog li 2000 txog 2500 degrees Celsius hauv huab cua inert. Thaum qhov kub siab no, kev ua carbonization tshwm sim, hloov cov khoom sib tov mus ua ib pawg khov kho.
5. Kev Sib Tsoo thiab Kev Sib Tsoo: Cov khoom uas tau ua los ntawm cov pa roj carbonized raug txias thiab tom qab ntawd raug sib tsoo kom tawg ua tej daim me me. Cov khoom no ces raug sib tsoo kom tau txais qhov loj me ntawm cov khoom me me uas xav tau. Cov khoom siv sib tsoo hu ua ntsuab silicon carbide.
6. Kev Sib Tsoo thiab Kev Faib Tawm: Cov silicon carbide ntsuab raug ua tiav ntxiv los ntawm kev sib tsoo thiab kev faib tawm. Kev sib tsoo cuam tshuam nrog kev txo qhov loj me ntawm cov khoom siv mus rau qib xav tau, thaum kev faib tawm cais cov khoom raws li qhov loj me.
Kev Ntxuav thiab Kev Ntxuav Acid: Txhawm rau tshem tawm cov khoom tsis huv thiab cov pa roj carbon seem, cov silicon carbide uas tau muab faib ua pawg tau dhau los ntawm cov txheej txheem ntxuav. Kev ntxuav acid feem ntau yog siv los tshem tawm cov khoom tsis huv thiab lwm yam khoom tsis huv.
7. Kev Qhuav thiab Ntim: Cov silicon carbide uas tau lim lawm raug ziab kom tshem tawm cov dej noo. Tom qab ziab, nws npaj txhij rau kev ntim khoom. Cov khoom kawg feem ntau yog ntim rau hauv hnab lossis thawv rau kev faib tawm thiab muag..
