Oneone Mullite
Oneone Mullitehe momo rauemi ātete aluminosilicate e whakamahia whānuitia ana i roto i te umanga whakarewa.
Te Hanganga Matū Matua:
Ko ngā wāhanga matū matua o te onepu mullite ko te Waikura Konumohe (Al₂O₃) me te Hāora Hiraka (SiO₂). Ko ngā awhe hanganga matū noa ko: 42% ≤ Al₂O₃ ≤ 47% me te 51% ≤ SiO₂ ≤ 53%. Kei roto hoki he iti noa te Waikura Rino (Fe₂O₃), ngā Waikura Konganuku Kawakore (Na₂O+K₂O), me ētahi atu huānga iti.
Tukanga Whakaputa:
Ko te onepu mullite te tikanga e hangaia ana mā te whakamahi i ngā kohuke whai kiko i te aluminosilicate, pērā i te kaolin, te uku mārō, te muscovite rānei. Ko te tukanga ko te kuru i ngā rauemi mata, te whakaranu i a rātou ki ngā tāpiringa, me te pēhi kia āhua. Kātahi ka whakakāhia ēnei āhua ki roto i te oumu pāmahana teitei i waenga i te 1300°C me te 1550°C. I muri i te whakakāhia, ka kuruhia te hua, ka tātarihia, ka wehea te aukume hei tango i te rino, me ētahi atu tukanga hei whiwhi i ngā hua onepu mullite o ngā rahi matūriki rerekē.
Ngā Whakatakotoranga Rahi Matūriki:
He whānuitanga ngā rahi o te onepu mullite. Ko ā mātou rauemi matua: 8-16 mata, 16-30 mata, 30-60 mata, 60-80 mata, me te 80-120 mata. Hei tāpiri, kei a mātou ētahi atu momo pai ake e mōhiotia ana ko te paura mullite, pērā i te 200 mata me te 300 mata.
Ngā Āhuatanga Mahi:
Teitei o te Ātete:He ātete ki te pāmahana tata ki te 1750°C, ā, ka tu atu i ngā pāmahana tiketike o te konganuku rewa i te wā e whakarewaina ana, e tiaki ana i te anga pokepokea ai mai i te kino.
Te Pūmautanga Wera Tino Pai:Ka mau tonu te pumau o te āhua o te onepu mullite ina pāngia e ngā huringa pāmahana. He ātete ki te horapa, ki te whakaheke rānei i te wera, kia tika ai te hanga o ngā mea whakarewa.
Ngāwari te Rūrū i te Taonga:I muri i te whakarewatanga, ka taea te tango ngāwari i te onepu mullite (ruperupea) mai i ngā whakarewatanga. Mā tēnei ka whakaitihia te hiahia mō ngā mahi whakaoti i muri mai, ā, ka pai ake te whai huatanga o te whakaputa.
Te Kounga Maka Teitei:Mā te whakamahi i te onepu mullite hei rauemi anga ka puta he mata maeneene. Ka whakaitihia ngā hapa whakarewa pērā i ngā kōhao onepu me ngā pūwero, ā, ka pai ake te kounga whānui o ngā whakarewanga.

Ko te kaupapa matua o te whakarewanga tika ko te hanga anga pokepokea ai (te tukanga paninga i te tauira ware pi ki ngā paparanga maha o te rauemi ātete hei hanga anga o waho. I muri i te rewa o te tauira ware pi, ka hangaia he kōhao hei ringihanga i te konganuku rewa). Ko te onepu mullite te mea matua e whakamahia ana hei whakakotahi ātete i roto i te anga pokepokea ai, ā, ka pania ki ngā paparanga rerekē o te anga, inā koa:
1. Anga Mata (Ka Whakatau Tika i te Kounga Mata o te Maka)
Mahi:Kei te pā tika te paparanga o te mata ki te mea whakarewa, ā, me whakarite kia maeneene te mata (kia kore ai e taratara, e pakaru), me te ātete hoki ki te pānga tuatahi o te konganuku rewa.
2. Anga o Muri (He Kaha Whānui, he Āhei hoki ki te Manawa)
Mahi:He hanganga maha-paparanga te anga o muri i waho o te paparanga mata. Ka tautoko i te kaha whānui o te anga pokepokea ai (ka ārai i te rerekētanga, i te hinga rānei i te wā e ringihia ana) me te whakarite hoki i te āheinga manawa (te tukunga hau mai i te kōhao me te ārai i te porosity i roto i te whakarewanga).
3. Ngā tono motuhake mō ngā whakarewanga e hiahiatia ana
Ngā whakarewa koranu pāmahana-tiketike:pērā i ngā mata o te mīhini rererangi (ngā pāmahana ringihanga o te 1500-1600°C), me tu te anga pokepokea ai i ngā pāmahana tino kino. Ka taea e te ātete teitei o te onepu mullite te whakakapi i te onepu zircon utu nui ake (te ira rewa 2550°C, engari he utu nui), ka tutuki i ngā whakaritenga ātete pāmahana teitei me te whakaiti i ngā utu.
Mō ngā whakarewa whakarewa tauhohe:pērā i ngā koranu konumohe me ngā koranu konupora (he tino tauhohe, ā, he ngāwari te tauhohe ki te SiO₂ i roto i te onepu kuata hei hanga whakaurunga), ka taea e te pumau matū o te onepu mullite te whakaiti i te tauhohenga me te ārai i te hanganga o ngā "whakaurunga waikura" i roto i te whakarewanga.
Mō ngā whakarewanga nui me te tika:pērā i ngā whare pouaka miihini o te tāhū hau (e hia tāne te taumaha), me nui ake te kaha o te hanganga o te anga pokepokea ai. He kaha te paparanga tautoko i hangaia e te onepu mullite me te mea here, e whakaiti ana i te tūponotanga o te horapa me te hinga o te pokepokea ai.
4. Te Whakakotahitanga me Ētahi Atu Rauemi Ātete
I roto i te mahi hanga tuturu, ka whakamahia te onepu mullite me ētahi atu rauemi hei whakapai ake i te mahi a te anga pokepokea ai:
Te whakakotahitanga me te onepu zircon:Ka whakamahia te onepu zircon hei paparanga mata (hei whakarite kia pai ake te āhua o te mata) me te onepu mullite hei paparanga tuara (hei whakaiti i ngā utu). He pai tēnei mō ngā whakarewanga he tino teitei ngā whakaritenga mata, pērā i ngā wāhanga rererangi.
Te whakakotahitanga me te onepu kiripaka:Mō ngā whakarewanga he iti iho te pāmahana e hiahiatia ana (pēnei i te koranu parahi, te ira rewa 1083℃), ka taea te whakakapi i te onepu kuata me te whakamahi i te whānui iti o te onepu mullite hei whakaiti i ngā kapiti anga.
