Pereki Korunuma/Pereki Korunuma Mullite
Ngā Mōhiohio Hua
Pereki korunumaHe hua ātete-waikura ngā s, ko te korundum te wāhanga tioata tuatahi, ā, neke atu i te 90% te ihirangi alumina.
Whakarōpūtanga:Ko ngā pereki kōrunamu ka whakarōpūtia ki ngā pereki kōrunamu kua whakatōngia me ngā pereki kōrunamu kua hanumi. Ko te mea tuatahi he mea hanga mai i te alumina kua whakatōngia, ko te mea tuarua he mea hanga mai i te kōrunamu kua hanumi. Ka taea hoki te hanga pereki kōrunamu kāore i tahuna mā te whakamahi i te waikawa phosphoric, i ētahi atu mea here rānei.
Ngā Āhuatanga Mahi:
Ngā Āhuatanga Pai o te Ātete-Pai:Neke atu i te 1700°C te pāmahana ngohengohe o ngā pereki kōrunuma i raro i te kawenga, ā, ka taea e ētahi pereki kōrunuma kōruma te eke ki te pāmahana neke atu i te 1790°C. Ka noho pumau tonu i roto i ngā taiao pāmahana teitei, ā, kāore e ngāwari ki te whakarerekē, ki te pakaru rānei.
Kaha Teitei:Ko te kaha pēhi o ngā pereki korundum parakore-teitei i te pāmahana rūma he 70MPa-100MPa te tikanga, ko te kaha pēhi o ngā pereki korundum chrome mahi-teitei he neke atu i te 150MPa, ā, ka eke ki te 340MPa.
Te Pūmautanga Matū Pai:He tino ātete ngā pereki korunuma ki ngā para waikawa, kawakore rānei, ki ngā konganuku me te karāhe rewa, ā, kāore e ngāwari ki ngā tauhohenga matū.
He ātete kaha ki te horo o te para:Hei tauira, ko te nui o te Cr₂O₃ i roto i ngā pereki kōruma korunuma ka ārai i te para rewa kei uru ki te tinana pereki mā roto i ngā pūwero, ā, ka hua ake he ātete pai ake ki te horo o te para i ngā pereki kōruma noa.
Ngā Kai Matua me ngā Rauemi Mata:
Ko te wāhanga matua o ngā pereki kōrunamu ko te alumina (Al₂O₃), he nui ake i te 90% te nui, ā, ko ētahi kei roto tae atu ki te 99%. Ko ngā rauemi mata ko te alumina kua whakakāhia me te kōrunamu kua hanumi. Ka taea hoki te tāpiri i ētahi atu rauemi kohuke hei hanga rauemi hiato, pērā i te Cr₂O₃ mō ngā pereki kōrunamu kōrome me te ZrO₂ mō ngā pereki kōrunamu kōroniuma.
Ngā pereki korundum-mulliteHe pereki ātete-wera whakakotahi tēnei, he mea tito mai i ngā āhua pumau e rua e pā ana ki te pāmahana teitei: te korundum (Al₂O₃) me te mullite (3Al₂O₃・2SiO₂). Ka whakakotahihia e rātou te kaha teitei o te korundum me te ātete pai rawa atu ki ngā ru wera o te mullite, ka waiho hei rauemi pāmahana teitei e whakataurite ana i te mahi me te whai huatanga utu.
Ngā Wāhanga Matua me ngā Āhuatanga Hanganga
Te Hanganga o te Āhuatanga Tioata Matua:Ko te korundum me te mullite ngā āhua matua e rua o te tioata, ko te ihirangi alumina kei waenga i te 70% ki te 90%, ā, ko te toenga ko te hauhā silicon (SiO₂). Mā te pānga mahi tahi o ngā āhua e rua ka taurite te mahi.
Hanganga iti:Ka tohatohahia ngā āhua mullite i waenga i ngā kōpura kōrundum i roto i te āhua o ngā tioata āhua ngira, o ngā tioata poutū rānei, ka hanga he hanganga "angihanga kōrundum + hononga mullite". Ehara i te mea ka whakarei ake i te kaha o te pereki anake, engari ka ārai hoki i ngā ahotea wera i roto i ngā āputa moroiti-kiriata.
Ngā Painga Matua o te Mahi
Te ātete tino pai ki te ru wera:Koinei tōna painga matua. He iti te tauwehenga whakawhanui wera o te Mullite, ā, ka mimiti te hanganga tioata āhua-ngira i te ahotea i puta mai i ngā piki me ngā heke o te pāmahana, ka whakaiti nui i te pakaru i puta mai i te whakamatao tere me te whakamahana i ngā pāmahana teitei. He nui ake tōna mahi i ngā pereki korundum parakore.
Kaha taurite me te ātete ki te waikura:Mā te noho mai o te wāhanga korundum ka tino kaha i ngā pāmahana rūma me ngā pāmahana teitei, ā, ka pai hoki te ātete ki te para waikawa, te karāhe rewa, me ētahi atu mea. Ahakoa he iti ake te ātete ki te kawakore i ērā o ngā pereki korundum kōroma, he whānui ake ngā whakamahinga.
Te kawe wera ngawari:Ki te whakatauritea ki ngā pereki korundum matotoru, he iti ake te kawe wera me te pupuri tonu i tētahi taumata whakamarumaru, ka whakaiti i te ngaronga wera i roto i ngā taputapu pāmahana teitei, ā, he pai hoki mō ngā tono e hiahia ana ki te whakamarumaru wera.
