Whakaahuatanga:
Ko nga whakamatautau e whakaatu ana ka huri te wahanga alpha ki te waahanga beta ki te hanganga pumau i te mea kei runga ake te pāmahana i te 1300 ℃. Ko te momo taapiri i whai mana ki te whakawhiti i te wahanga alpha ki te beta o te SI3N4, a ko te painga o te Y2O3 i runga i te waahanga whakawhiti ko te nuinga. kitea.
Ko te Alpha Silicon Nitride Paura te paura no nga puhui whakaahuru teitei, kaore he ira rewa, ko te SI3N4 te whakamahi i te pāmahana kaore i neke atu i te 1300 ° C.
I tua atu i te waikawa waiwaro, karekau te nitride silicon e waikura e etahi atu waikawa me nga turanga.
Tikanga Rokiroki:
Ko te paura Silicon Nitride me rongoa ki roto i te hiri, karohia te waahi marama, maroke.He pai te rokiroki i te pāmahana rūma.
