Paura Alumini mō te whakakanapa
He pai rawa te paura alumina mō te hanga konumohe me ētahi atu e hiahia ana kia pakeke, kia ātete hoki ki te waikura, ki ētahi atu momo kakahu matū rānei. He pai hoki te paura alumina mō ngā hua e hiahia ana kia ātete ki te waikura me te kakahu, me ngā hua e hiahia ana kia nui te kawe wera, pērā i ngā tono whakamahana hiko me te wera.
Te mahi a te hua:
He paura mā, he onepū pai rānei te hua, ā, he pai te mahi whakapūkara. Kāore e rewa i te wai, kāore hoki e rewa i te waikawa, i te kawakore rānei. Ka taea te whakahaere i te rahi o te matūriki o te protocrystal.

Ngā Āhuatanga o te Paura Alumina:
1. Ātete matū
2. Alumina tino parakore, he nui ake te ihirangi alumina i te 99%
3. Ātete pāmahana teitei, ko te pāmahana mahi he 1600 ℃, tae atu ki te 1800 ℃
4. ātete ki te ru wera, pumau, uaua hoki ki te pakaru
5. Te whakahāngai mā te whakarewa, he tino matotoru
He tino parakore te paura alumina, ā, he tino matotoru, e whakamahia ana i roto i ngā uku, i te karāhe, i ngā kirihou, i ngā kakahu, i ngā rauemi hanga, i ngā mea whakakoi, i te pepa me te rongoā, me te maha atu o ngā mara.
Painga o te Paura Alumina:
1. Mā te mira rere hau me te whakarōpūtanga paparanga e rima, he whaiti te tohatoha rahi o te witi, he teitei te pai o te huri, he pai te pānga oro, he teitei ake te pai o te huri i ngā mea whakakoi ngohengohe pēnei i te silica.
2. He āhua pai te matūriki, he maeneene te mata o te mea e whakakanapahia ana, ā, i te tukanga whakakanapa pai whakamutunga, he pai ake te hua o te huri me te whakakanapa i te paura korundum ma.
1. Te whakakanapa i te mata waea, tae atu ki te whakakanapa whakamutunga mō te mata waea pūkoro hapaira, te mata karāhe waea pūkoro. Ka taea hoki te whakamahi: ngā kohatu horihori, te zircon, te karāhe kounga teitei, ngā kōhatu tūturu, te jade, te agate me ētahi atu whakaotinga wiri (te whakakanapa mīhini, te whakakanapa hurihuri), te whakakanapa ā-ringa (te whakakanapa huri) me ētahi atu.
2. Te whakakanapa whakarewa, tae atu ki te anga waea pūkoro, ngā wira motuka, te whakakanapa whakamutunga taputapu kounga teitei.
3. E whakamahia whānuitia ana i roto i te huri me te whakakanapa i ngā mea haurua-ira, tioata, konumohe, maitai, kowiri tira, kohatu, karāhe, me ētahi atu.
4. He tino pai mō te huri me te whakakanapa i te kowiri tira, te parahi, ētahi atu rauemi whakarewa, me te umanga karāhe me te whakaata.
