Kirikiri alumina parauri kua whakaranua mō te wira huri pepa kirikiri kua pania ki te kirikiri
Ko te alumina parauri kua hanumi/korundum parauri, e mōhiotia whānuitia ana ko te emery, he korundum hangai parauri i hangaia mā te whakarewa me te whakaiti i ngā rauemi mata e toru: te bauxite, te rauemi waro me ngā kongakonga rino i roto i te oumu hiko, nō reira te ingoa. Ko tōna wāhanga matua ko te alumina, ā, ka wehewehea hoki ngā tohu e te nui o te konumohe. Ko te iti o te nui o te konumohe, ko te iti o te pakeke. Ka hangaia te rahi o te matūriki hua e ai ki ngā paerewa o te ao me ngā paerewa ā-motu, ā, ka taea te tukatuka e ai ki ngā hiahia o te kaiwhakamahi. Ko te rahi whānui o te matūriki ko te F4~F320, ā, ka rerekē te hanganga matū i runga i te rahi o te matūriki. Ko te āhuatanga tino pai ko te iti o te rahi tioata me te ātete ki te pānga. Nā te mea ka tukatukahia, ka pakaruhia hoki e te mīhini huri-ake, ko te nuinga o ngā matūriki he matūriki porowhita. He maroke, he ma te mata, ā, he ngāwari ki te hono atu ki te here. Ko te alumina parauri kua hanumi he mea hanga ki te bauxite karaehe whakakoi hei rauemi mata, ā, ka tāpirihia ki ngā rauemi āwhina. Ka whakatikatikaina i roto i te oumu hiko i te pāmahana teitei i runga ake i te 2250℃. I runga i tēnei kaupapa, ka whakatikatikaina mā te whakamahi i tētahi wehenga aukume kaha-teitei, ā, ko tōna ātete he neke atu i te 1850℃. Ko te kōrunuma parauri i hangaia e tā mātou kamupene he āhuatanga o te parakore teitei, te tioata pai, te rere kaha, te tauwehenga whānui iti me te ātete waikura. Ko ngā āhuatanga o te hua he kore-pahū, he kore-paura, he kore-ngatata i te wā tono, ā, he maha ngā wā e whakamahia ana i roto i ngā ahumahi mea whakakoi me ngā rauemi mata ātete.

Ngā rauemi whakakoi: Wira huri, whitiki whakakoi, pepa kirikiri, kakahu whakakoi, wahi tapahi, hangarau pupuhi kirikiri, huri, papa ātete-kakahu, tapahi pupuhi wai, whakakoi pania, whakakoi whakakotahi, me ētahi atu.
Ngā rauemi ātete ahi: Ka taea te whakarewa, te pereki ātete ahi, te rauemi tāmi, te pereti reti, te pūwero, te koko, te rauemi arai, te whakarewa tika, me ētahi atu
Ko te kōrunuma parauri e kiia ana ko ngā niho ahumahi: e whakamahia ana i roto i ngā whare tahu ahi, ngā wira huri, me te pupuhi onepu.
1. Whakamahia hei hanga rauemi ātete matatau, mea whakarewa, pereki ātete, me ētahi atu.
2. Te pupuhi onepu—he pakeke taurite te mea whakakoi, he nui te kiato papatipu, kāore he silica kore utu, he nui te taumaha motuhake, ā, he pakari pai. He rauemi pupuhi onepu "hoa taiao" tino pai. He whānuitia te whakamahinga i roto i ngā kōtaha konumohe, ngā kōtaha parahi, te karāhe, me ngā tarau horoi. Ngā pokepokea tika me ētahi atu mara;
3. He mea whakakoi kore utu, e whakamahia ana mō te huri kore utu i roto i ngā mara o te ngongo pikitia, te karāhe whatu, te silicon monocrystalline, te arotahi, te karāhe mataaratanga, te karāhe tioata, te jade, me ētahi atu. He rauemi huri kounga teitei e whakamahia whānuitia ana i Haina;
4. Ngā Kaihoroi Resin - He kaihoroi he tae e tika ana, he pakeke, he pakari, he momo whakawhiti-wāhanga matūriki e tika ana me te pupuri taha, ka whakamahia ki ngā kaihoroi resin, he tino pai te hua;
5. Ngā mea whakakoi pania—he rauemi mata ngā mea whakakoi mā ngā kaihanga pērā i te pepa kirikiri me te kākano;
6. Whakakī mahi - e whakamahia ana mō ngā wāhanga pērai motuka, ngā potae motuhake, ngā hua hanga motuhake me ētahi atu kara, ka taea te whakamahi hei rauemi ātete-kakahu pēnei i ngā ara rere, ngā tauranga, ngā papa waka, ngā papa ahumahi, ngā wāhi hākinakina, me ētahi atu;
7. Pāpāho tātari - he mara tono hou mō ngā mea whakakoi. Ka whakamahia ngā mea whakakoi kirikiri hei pāpāho raro o te moenga tātari hei pure i te wai inu, i te wai para rānei. He momo rauemi tātari wai hou i te kāinga me tāwāhi, he tino pai mō te tukatuka kohuke konganuku kore-ferrous: te kaihoko taumaha paru keri hinu:
8. Te tapahi waipēhi - ka whakamahia ngā mea whakakoi hei rauemi tapahi, ā, ka whakawhirinaki ki ngā pupuhi wai pēhanga teitei mō te tapahi taketake. Ka whakamahia ki te tapahi i ngā paipa hinu (hau māori), te maitai me ētahi atu wāhanga. He tikanga tapahi hou, he pai mō te taiao, he haumaru hoki.
