Te mahi a te hua:He kaha tōna pumau ki te pāmahana teitei, he ātete pai ki te ru wera, te ātete ki te kakahu, te ātete ki te waikura matū me ētahi atu āhuatanga.
Ngā whakamahinga matua:E whakamahia ana i ngā rohe whakawhiti o ngā oumu hurihuri sima, ngā oumu pirau, ngā paipa hau tuatoru, me ētahi atu taputapu wera e hiahia ana ki te ātete ki ngā ru wera.
Ngā āhuatanga o te hua:Hei rauemi taketake mō te umanga ātete-whakarewa, he āhuatanga ngā pereki alumina teitei o te ātete-whakarewa, he pāmahana whakangawari-kawenga teitei (tata ki te 1500°C), ā, he ātete pai ki te horo. He whānuitia te whakamahinga i roto i ngā oumu ahumahi i roto i ngā momo ahumahi. Heoi, nā te nui o te ihirangi āhua korundum o ngā pereki alumina teitei noa, he nui ake ngā tioata āhua korundum i roto i ngā hua kua whakatōngia, ā, he ngāwari te pakaru me te kiri ina tūtaki ki ngā āhuatanga whakamatao me te whakamahana tere. Ko te pumau o te ru wera i raro i ngā āhuatanga whakamatao wai 1100°C ka taea te eke ki te 2-4 ngā wā. I roto i te pūnaha whakaputa sima, nā te iti o te pāmahana whakatōngia me ngā whakaritenga mahi kia piri ai ngā rauemi ātete-whakarewa ki te kiri oumu, ka taea anake te whakamahi i ngā pereki alumina teitei i roto i te rohe whakawhiti o te oumu hurihuri, te hiku oumu me te whakamahana-mua o te oumu pirau.
Ko ngā pereki konumohe teitei ātete-whakangaromanga he pereki konumohe teitei me ngā āhuatanga ātete-whakangaromanga i hangaia i runga i te kinker konumohe teitei me te tāpiri atu ki te ZrO2 me ētahi atu rauemi rānei. Ka taea te wehewehe kia rua ngā wāhanga, ko tētahi he pereki konumohe teitei ātete-whakangaromanga kei roto ko te ZrO2, ko tētahi he pereki konumohe teitei ātete-whakangaromanga kāore he ZrO2.
Ka taea e ngā pereki alumina teitei-ātete-whakarewa te ātete i ngā kawenga wera pāmahana teitei, kāore e mimiti te rahinga, ā, he rite te whānui, kāore e ngokingoki, e hinga rānei, he tino kaha pāmahana noa me te kaha wera pāmahana teitei, he pāmahana whakangawari kawenga teitei, ā, he pai te ātete wera. Ka taea e ia te ātete i te pānga o ngā huringa pāmahana ohorere, te wera koretake rānei, ā, kāore e pakaru, e tihore rānei. Ko te rerekētanga i waenga i ngā pereki alumina teitei-ātete-whakarewa kei roto ko te ZrO2 me ngā pereki alumina teitei-ātete-whakarewa kāore he ZrO2 kei roto i ō rātou tikanga ātete-whakarewa rerekē. Ka whakamahia e ngā pereki alumina teitei-ātete-whakarewa kei roto ko te ZrO2 ngā rauemi zircon hei whakamahi i te ātete waikura pai rawa atu. Ka ātete te ZrO2 i te mimiti o te whanariki-chlor-alkali. I taua wā anō, i ngā pāmahana teitei, ka huri te SiO2 kei roto i te zircon i te āhua tioata mai i te cristobalite ki te āhua quartz, ka hua ake he pānga whānui rōrahi, ā, ka whakaiti i te mōrearea o te ārai whanariki-chlor-alkali. I taua wā anō, ka ārai i te pakaru i te wā wera me te makariri; Ko ngā pereki alumina teitei ārai-whakapakari kāore nei he ZrO2 ka hangaia mā te tāpiri i te andalusite ki ngā pereki alumina teitei. Ka whakamahia te andalusite i roto i te hua mō te whakapūtanga tuarua i roto i te oumu sima. Ka puta he pānga whakawhanui-iti kore e taea te hoki, kia kore ai te hua e mimiti ina whakamataohia, ka whakakore i te ahotea mimiti me te ārai i te kiri o te hanganga.
Ki te whakaritea ki ngā pereki alumina nui-whakamaroke kāore nei he ZrO2, he pai ake te ātete o ngā pereki alumina nui-whakamaroke kei roto he ZrO2 ki te urunga me te memeha o ngā wāhanga whanariki, te chlorine me te alkali, nō reira he pai ake ngā āhuatanga ārai-maroke. Heoi, nā te mea he rauemi onge te ZrO2, he utu nui, nō reira he nui ake te utu me te utu.Ko ngā pereki ā-konumohe nui ārai-whakapakari kei roto ko te ZrO2 ka whakamahia anake i roto i te rohe whakawhiti o ngā oumu hurihuri sima. Ko ngā pereki ā-konumohe nui ārai-whakapakari kāore i roto ko te ZrO2 ka whakamahia i roto i ngā oumu pirau o ngā raina whakaputa sima.
