He iti ngoki pereki alumina teitei (T-38)
NGA HUA
He Pereki Konumi Teitei Ngakoti Iti (T-38)
Whakaahuatanga mo te Pereki Alumina Te Ngako Raiti
Ko te iti o te ngokingoki pereki alumina teitei he mea hanga mai i te alumina, te konumohe whakakotahi, te mullite te whakakotahi hei rauemi mata matua o nga hua whakaahuru ahua, ko te waahanga matua ko Al2O3.Ko nga hua pereki alumina teitei he painga o te ngokingoki iti o te pāmahana, te kaha o te waikura me te pai o te wiri waiariki.
