Thepa ea recrystallized silicon carbide
Recrystallized silicon carbide (R-SiC) ke sesebelisoa se sebetsang hantle se nang le boima ba bobeli ho daemane, se entsoeng ka mocheso o phahameng ka holimo ho 2000 ℃. E na le lisebelisoa tse ngata tse ntle tsa SiC, joalo ka matla a mocheso o phahameng, khanyetso e matla ea kutu, khanyetso e ntle ea oxidation, ho hanyetsa mocheso o motle joalo-joalo.

Tlhaloso ea Sehlahisoa:
Re thabela ho u tsebisa sehlahisoa sa morao-rao se entsoeng ke Semicera Energy Technology Co., Ltd. - Semiconductor SiC.Sekepe sa Wafer. Joaloka morekisi ea ka sehloohong ea sebetsanang le li-wafers le lisebelisoa tse tsoetseng pele tsa semiconductor, re ikemiselitse ho fa bareki lihlahisoa tsa boleng bo holimo, tse tšepahalang. , le ho sutumelletsa lihlahisoa tse ncha ho tlhahiso ea semiconductor, indasteri ea photovoltaic le likarolo tse ling tse amanang le tsona.
Semiconductorsekepe sa silicon carbide wafers li etsoa ka ho sebelisa silicon carbide e nchafalitsoeng (R-SiC), thepa e sebetsang hantle e nang le thepa e ikhethang.
