Te tono hua
E whakamahia whānuitia ana ngā ngongo hapaira i roto i ngā ahumahi mahi-teitei pēnei i te tukatuka haurua-ira, te rererangi, te whatu, me te miihini matū. Nā tō rātou kaha ki te tu atu i ngā pāmahana tino nui (tae atu ki te 1,600°C), me te ātete matū tino pai ki ngā waikawa me ngā kawakore, he mea pai mō ngā oumu pāmahana-teitei me ngā taiao waikura. Hei tāpiri, nā tō rātou māramatanga pai puta noa i ngā roangaru UV ki te IR he mea nui ki ngā pūnaha whatu. He mea nui hoki te kaha miihini teitei me te kawe wera o te ngongo hapaira mō ngā tono e hiahiatia ana te roa me te marara wera, pēnei i roto i ngā hikohiko me ngā pūnaha hiko.
Whakarāpopototanga Whānui
Ko te ngongo hapaira, he mea hanga mai i te hapaira karaihe kotahi Al₂O₃ parakore 99.999%, he rauemi tino pai i hangaia mō te whakamahi i roto i ngā ahumahi mahi teitei pēnei i ngā semiconductors, te rererangi, te whatu, me te miihini matū. Me te pakeke o te 9 i runga i te tauine Mohs, he pai ake te ātete ki te rakuraku me te kaha miihini. Ka taea e ia te mahi i roto i ngā taiao tino kino me te pāmahana tae atu ki te 1,600°C, he mea tino pai mō ngā oumu pāmahana teitei me ngā tautuhinga waikura nā te mea he tino ātete ki te matū.
Hei tāpiritanga, ko te kawe wera o te ngongo hapaira o te 46 W/m·K ka whakarite kia pai te marara o te wera, ā, ko tōna māramatanga teitei puta noa i ngā roangaru UV ki te IR ka tautoko i ngā tono whatu nui. I te whakakotahitanga me ōna āhuatanga dielectric tino pai, he otinga pakari tēnei hua mō ngā hikohiko, ngā pūnaha hiko, me ngā whatu. Mā te roa, te pumau, me te mahi nui, ka tukuna e ngā ngongo hapaira te pono i roto i ētahi o ngā taiao ahumahi me te hangarau tino uaua.
