1. Kupu Whakataki
Ehara i te mea he rauemi mata noa te konumohe mō te hanga konumohe; he pou tūāpapa hoki mō te hanga hangarau hou. Mai i ngā hikohiko iti me te rokiroki pūngao ki ngā whatu, te whakatere, me ngā paninga tiaki, nā te huinga ahurei o ngā āhuatanga o te konumohe he mea tino nui. I te tipu haere o te hiahia mō te whakaitiiti, te whai huatanga o te pūngao, me te pono nui i roto i ngā pūnaha hiko me te pūngao, kāore anō kia nui ake i tēnei wā te hiahia mō te konumohe parakore kua hangaia kia tika.
2. Ngā Āhuatanga me ngā Whakatakotoranga o ngā Rauemi
Ka whakarōpūtia te alumina parakore-teitei e tōna āhua, te taumata parakore, te tohatoha rahi matūriki, me te ihirangi paru iti, ia tawhā i whakaritea ki ngā whakaritenga tono motuhake.
2.1 Te Whakahaere i te Parakore me te Parakore
- Ngā Wāhanga Parakore Teitei: He mea nui te alumina 4N (99.99%), 5N (99.999%), me te 6N (99.9999%) mō ngā tono tairongo pērā i te whakakī i ngā haurua-haurua me ngā wāhanga whatu.
- He iti te tukunga o te hihi-ārai: He mea nui mō te takai haurua-ira hei ārai i ngā hapa ngohengohe i roto i ngā taputapu mahara. He maha ngā wā e hiahiatia ana e ngā whakatakotoranga he iti iho i te 3 ppb te nui o te ūranium (U) me te thorium (Th), me te iti rawa o ngā poke Fe, Na, me te Cl.
- Tauira Whakatakotoranga:
