Product Description
Peb lub tuam txhab muab SiC txheej txheej txheem kev pab cuam los ntawm CVD txoj kev nyob rau saum npoo ntawm graphite, ceramics thiab lwm yam ntaub ntawv, kom tshwj xeeb gases uas muaj carbon thiab silicon react ntawm kub kom tau siab purity SiC molecules, molecules tso rau saum npoo ntawm cov ntaub ntawv coated, tsim SIC tiv thaiv txheej.
Cov yam ntxwv tseem ceeb:
1. Kub oxidation kuj:
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.
