Whakaahuatanga Alumina Ripanga Kua Whakatōngia
Kōrunuma ripanga, e mōhiotia ana hoki koalumina ripanga kua whakatōngia, he momo alumina tino parakore (Al2O3) kua tukatukahia kia whaiāhua papatahi, āhua motuhake rāneiKa puta mā te whakamahana (te whakamahana me te kore e rewa) i te paura alumina kounga teitei i ngā pāmahana neke atu i te 1900°C, ka tupu ngā matūriki alumina, ka hanga he tioata nunui, papatahi, rite ki te pereti.

| WhakamahingaE whakamahia whānuitia ana te kōrunuma ripanga i roto i ngā rauemi ātete-kaha teitei i roto i ngā mara ote maitai, te whakarewa, ngā matū hinu, ngā pereki manawa, ngā arai koko, ngā mea whakarewa, ngā wāhanga kua oti te hanga, ngā uku me ētahi atu maraHe rauemi mata pai rawa atu tēnei e kore e pakaru te kiri. Ka whakamahia te kōrunuma ripanga heiTe whakakotahitanga āteteka taea te whakamahi tahi me te spinel, te alumina whakahohe kua whakapūkarahia, me ngā mea here pēnei i te sima, te uku, te kapia rānei. He iti te poke o ngā pereki korundum parakore kua oti te whakarite (pēnei i te SiO2), he nui te matotoru, ā, he pai ngā āhuatanga thermodynamic, e hanga ana i ngā pereki korundum he ātete ki ngā kino wera, matū me te hanganga i puta mai i te whakahaere o ngā oumu hau me ētahi atu oumu ahumahi. | ||
| Ngā Painga:he ātete nui ki te waikura; he ātete nui ki te horo; he ātete nui ki te ru wera; he kaha nui, he pakari pai; he āhuatanga matū pumau; ātete ki te horo o te para kawakore, ātete pai ki te horo o te para, me te ātete pai ki te horo o te rino rewa; ātete ki te horo o te maitai rewa, ā, pai te uruhanga o te hau. | ||
