Ngā oumu hurihuri simako ngā taputapu matua o te hanga sima, e mahi ana i raro i ngā āhuatanga tino kino—te pāmahana tae atu ki te 1450°C, te horo matū nui mai i ngā rauemi kawakore me te kinker, me te mau tonu o te miihini. He mea nui te whiriwhiri i ngā pereki ātete tika hei whakarite i te mahi pumau, te whakaroa i te roa o te mahi oumu, me te whakaiti i ngā utu tiaki. Kei raro nei ngā momo matua o ngā pereki ātete i hangaia mō ngā oumu hurihuri sima, ia mea i hangaia mō ngā rohe mahi motuhake.
Pereki Alumina TeiteiKo ngā pereki ātete-waikura te mea e whakamahia whānuitia ana i roto i ngā oumu hurihuri sima. He 48% ki te 75% te nui o te alumina, ā, he tino pai te ātete ki te pāmahana teitei, te pumau pai o te ru wera, me te ātete kaha ki te kakahu. Ka whakamahia whānuitia ēnei ki ngā rohe iti ake te kaha pērā i te tomokanga oumu, te whakamahana-mua, me te oumu pirau, kei reira ngā pāmahana mai i te 800°C ki te 1200°C. Ko te iti o te porosity ka ārai i te urunga hau waikura, he mea pai mō ngā wāhi he iti te horo o te matū.
Ngā Pereki Spinel Konupora-Aluminahe mea nui mō te rohe tahunga o te oumu, ina tae te pāmahana ki te 1350°C ki te 1450°C. He mea hanga mai i te konupora waikura me te alumina, he ātete pai ki ngā ru wera, ā, ka taea te hanga i tētahi paparanga tiaki ina tauhohe ki te kirīni, ka ātete pai ki te horo o te kirīni rewa. Ki te whakatauritea ki ngā pereki konupora-kōrome, he pai ake te ātete ki te pakaru, ā, he pai ake te whiringa mō ngā rohe pāmahana teitei.
Ngā Pereki Konupora-Kromi Hononga TikaHe tino pai te ātete ki te waikura matū. He mea hanga mai i te konupūmā me te kōromita kounga teitei, i whakawerahia i te 1750-1850°C, he pai mō te rohe mura me te rohe whakawhiti, te wāhi e tino pāngia ai te waikura kawakore me te konupūmā. He pāmahana whakangawari teitei tō rātou, ā, he kaha miihini pai hoki, e whakarite ana i te pumau mō te wā roa i roto i ngā taiao uaua.
Ngā Pereki Ātete-Kawakawakua hangaia mō te paipa hau tuatoru me te wehewehe āwhiowhio, te wāhi e kitea nuitia ana te mimiti o te kohu kawakore. Me te 25%-30% alumina me te neke atu i te 65% silica, ka hangaia he paparanga kirikiri matotoru hei aukati i te urunga o te kawakore, hei ārai i te pakaru me te pakaru o ngā pereki.
Mā te whiriwhiri i ngā pereki ātete-hau e tika ana i runga i ngā rohe oumu ka pā tika ki te pai o te whakaputa me te utu. Ka tutuki ā mātou pereki ātete-hau mahi teitei i ngā paerewa ahumahi, me ngā otinga kua whakaritea mō ngā momo oumu rerekē. Whakapā mai ki a mātou i tēnei rā kia whiwhi ai i ngā hua ātete-hau pono e whakaiti ana i te wā kore mahi, e whakanui ake ana hoki i te pai o tō whakaputa sima.
