Pereki Ātete-Uku
Pereki uku ahiHe rauemi ātete-silico-aluminous ēnei, ā, he 35%–45% te nui o te Al₂O₃. Ko te nuinga o ēnei he mea hanga mai i te kaolin, he mea hanga kia rite te āhua, he mea whakamaroke, kātahi ka tahuna ki te pāmahana teitei o te 1300–1400℃. I te wā o te tukanga tahunga, ka hangaia he tioata mullite. Me te ātete-waikura o te 1690–1730℃, ka whakarōpūtia ngā pereki uku ahi hei hua ātete-waikura waikawa ngoikore.
Whakarōpūtanga
E whā ngā momo o ngā pereki uku ahi: te pereki noa, te pereki mātotoru, te pereki iti te ngoki, me te pereki ātete ki ngā ru wera, ā, he maha ngā momo pereki uku kei roto te Al₂O₃ mai i te 25% ki te 45%. E ai ki ngā āhuatanga tono, e toru ngā momo pereki uku: te pereki mō ngā oumu pupuhi, te pereki wera, me te pereki karāhe.
Ngā Āhuatanga Matua:
He tino pai te ātete o ngā pereki uku ahi ki te para waikawa me te waikura hau waikawa, engari he iti noa te ātete ki ngā matū kawakore. He pai te ātete ki ngā ru wera: i te awhe pāmahana 0–1000℃, ka whānui haere tonu te rōrahi i te pikinga o te pāmahana, me te tere whānui rārangi o te 0.6%–0.7%, tata ki te haurua o te pereki silica. Heoi, ko tō rātou ātete i raro i te kawenga he iti ake i te 200℃ i te pereki silica, ā, ka heke te rōrahi ina neke ake te pāmahana i te 1200℃.
