Kei roto i ngā pereki ātete piko te Al2O3 tata ki te 30% ~ 45%, ā, he iti iho i te 78% te nui o te silica. Nō roto i ngā rauemi ātete waikawa ngoikore ngā pereki ātete piko. He ātete te poraka ātete piko ki te paru waikawa me te mimiti o ngā hau waikawa, engari he ngoikore te ātete ki te kawakore. He pai te mahi wera me te ātete ki ngā ru wera o ngā poraka ātete piko.
Ngā Āhuatanga o te Pereki Ahi Piko
- Te ātete nui,
- He ātete pai ki te waikura,
- He ātete pai ki te ru wera,
- Te kaha miihini teitei,
- He iti te tere ngoki i te pāmahana tiketike,
- He ātete pai ki te pakaru me te ātete ki te kakahu.

Te Whakamahinga o te Pereki Ahi Piko
Ko te pereki ahi piko te nuinga o te wā e whakamahia ana mō te arai whakamahana o ngā mata wera, mō te tautoko rānei i ngā paparanga whakamahana o ētahi atu rauemi ātete ahi. Ko ngā arai ātete ahi, ngā rauemi whakamahana rānei o ngā ahumahi, pērā i ngā oumu pyrolysis ethylene, ngā oumu ngongo, ngā oumu whakahou haukini hangai, ngā whakaputa hau me ngā oumu angiangi pāmahana teitei, me ētahi atu.
