Kev piav qhia

Peb lub tuam txhab muabSiC txheejtxheej txheem kev pab cuam los ntawm CVD txoj kev nyob rau saum npoo ntawm graphite, ceramics thiab lwm yam ntaub ntawv, thiaj li hais tias tshwj xeeb gases uas muaj carbon thiab silicon react nyob rau hauv high kub kom tau siab purity SiC molecules, molecules tso rau saum npoo ntawm cov ntaub ntawv coated, tsim.SIC tiv thaiv txheej.

Lub ntsiab nta

1. Kub kub oxidation tsis kam:
oxidation kuj tseem zoo heev thaum kub siab li 1600 C.
2. High purity: ua los ntawm cov tshuaj vapor deposition nyob rau hauv siab kub chlorination mob.
3. Erosion kuj: siab hardness, compact nto, zoo hais.
4. Corrosion kuj: acid, alkali, ntsev thiab organic reagents.
