Ngā Pātai Auau mō ngā Mōhiti Quartz
P1: He aha te rerekētanga i waenga i ngā pereti RBSiC me ngā pereti SSiC?
A:He pai te kaha ā-pūkaha o te RBSiC, ā, he pai hoki te utu, engari he nui ake te parakore o te SSiC, he pai ake te ātete ki te waikura, ā, he kaha ake hoki. He pai ake te SSiC mō ngā tono haurua-ira me ngā tono matū.
Q2: Ka taea e ngā pereti uku SiC te tu atu i te ru wera?
A:Āe. He iti te horapa wera o te SiC, he nui hoki te kawe wera, e whakarite ana i te ātete pai ki ngā ru wera.
Q3: Ka taea te whakakanapa i ngā pereti mō ngā mahi mata whakaata?
A:Āe. Ka taea e te CVD-SiC me te SSiC tino-parakore te whakatutuki i te oro whakaata-whakaata mō ngā whakaritenga whatu, haurua-ā-ira rānei.
Q4: E tautoko ana koe i te miihini ritenga?
A:Āe. Ka taea te hanga pereti kia rite ki ō tuhi, tae atu ki ngā kōhao, ngā mokowā, ngā kōhao me ngā āhua motuhake.
