Taw qhia rau semiconductor-qib glassy carbon txheej

I. Taw qhia txog cov qauv iav iav

Yam ntxwv:

(1) Qhov saum npoo ntawm iav carbon yog du thiab muaj cov qauv iav;

(2) Glassy carbon muaj siab hardness thiab tsis muaj plua plav tsim;

(3) Glassy carbon muaj tus nqi loj ID / IG thiab qib qis ntawm graphitization, thiab nws cov thermal rwb thaiv tsev ua tau zoo dua;

(4) Glassy carbon yog ib qho nyuaj-rau-graphitize carbon nrog zoo kub tsis kam thiab muaj zog stability ntawm kub kub;

(5) Glassy carbon muaj cov tshuaj tiv thaiv me me ntawm thaj chaw thiab cov tshuaj tiv thaiv zoo heev, thiab tiv taus kev yaig los ntawm oxygen, silicon, thiab lwm yam.

II. Taw qhia rau glassy carbon txheej

Cov pores saum npoo ntawm flake graphite txheej yog faib thiab cov qauv yog xoob, thaum cov qauv ntawm cov iav carbon txheej yog nruj thiab tsis poob!

1. Anti-oxidation kev ua tau zoo ntawm glassy carbon txheej

(1)Laminated nyuaj xav
Glassy carbon txheej zoo txhim kho cov kev tiv thaiv oxidation ntawm cov tawv tawv;

(2)Luv fiber ntau nyuaj xav
Cov kev xav tag nrho muaj qhov porosity siab thiab muab cov pa oxygen; cov flake graphite txheej muaj cov qauv xoob, tsawg dua cov pa oxygen, thiab txhim kho kev ua haujlwm ntawm oxidation; Qhov txheej txheej iav carbon txheej muaj cov qauv tuab, cov pa roj oxygen tsawg, thiab kev tiv thaiv oxidation zoo tshaj plaws.

2. High-kub stability ntawm glassy carbon txheej tiv thaiv ablation
Cov qauv ntxeem tau ntawm lub tiaj tiaj muaj peev xwm ua kom muaj cua sov (kub convection tshav kub dissipation); graphite daim ntawv yog nquag blistering thaum ablated; ablation qhov tob ntawm glassy carbon txheej yog qhov ntiav tshaj, thiab nws ablation kuj yog qhov muaj zog tshaj; lub glassy carbon txheej muaj zoo thermal rwb thaiv tsev kev ua tau zoo.

3. Anti-Si yaig kev ua tau zoo ntawm glassy carbon txheej
Cov tawv tawv luv luv yog eroded thiab hmoov los ntawm Si; flake graphite txheej muaj kev tiv thaiv rau Si yaig nyob rau hauv lub sij hawm luv luv; glassy carbon txheej muaj qhov zoo tshaj plaws los tiv thaiv kev yaig.

Qhov laj thawj tseem ceeb ntawm Si yaig yog tias Si gasification ncaj qha erodes saum npoo ntawm cov tawv tawv, ua rau hmoov av; thaum cov qauv carbon ntawm glassy carbon txheej yog ruaj khov thiab muaj kev ua haujlwm zoo dua los tiv thaiv kev yaig.

Cov ntsiab lus

Glassy carbon txheej txheej tsis yog tsuas yog siv rau thermal rwb thaiv tsev cov ntaub ntawv, tab sis kuj yuav tsum tau siv ncaj qha rau ntawm qhov chaw ntawm graphite thiabC/C qhov chaw, zoo txhim kho cov kev pabcuam zoo ntawm cov khoom siv.
