Kei te wātea ngā paraikete muka uku i roto i ngā momo taumata rerekē, ia taumata i hangaia mō ngā whakaritenga tono motuhake. Ka rerekē pea te maha o ngā taumata i runga i te kaihanga, engari i te nuinga o te wā, e toru ngā paraikete muka uku matua:
1. Paerewa Paerewa: Paerewa paerewaparaikete muka ukuhe mea hanga mai i ngā muka uku ina-silica, ā, he pai mō te whakamahi i ngā tono me ngā pāmahana tae atu ki te 2300°F (1260°C). He pai te ārai wera me te ātete ki ngā ru wera, he mea tino pai mō ngā kaupapa ārai wera.
2. Teitei o te Parakore: Ko ngā paraikete muka uku tino parakore i ahu mai i ngā muka alumina-silica parakore, ā, he iti ake te nui o te rino i ērā o te paerewa. Nā tēnei ka pai mō ngā mahi e hiahia ana kia teitei ake te parakore, pērā i te rererangi, i te hikohiko rānei. He rite tonu te kaha pāmahana ki ērā o ngā paraikete paerewa.
3. Teitei o te Zirconia: He mea hanga ngā paraikete muka uku o te Zia mai i ngā muka zirconia, e whakarato ana i te pumau wera me te ātete ki te whakaeke matū. He pai ēnei paraikete mō ngā whakamahinga me ngā pāmahana tae atu ki te 2600°F (1430°C).
Haunga ēnei momo, he rerekētanga anō hoki ngā kōwhiringa kiato me te matotoru hei whakatutuki i ngā whakaritenga whakamarumaru motuhake.
