He ātete waikawa te pereki ātete-kirika, ā, he pai te ātete ki te waikura o te para waikawa. Ko te ātete o ngā pereki ātete-kirika i raro i te kawenga he tae atu ki te 1640~1690℃, ko te pāmahana whakangawari tuatahi ko te 1620~1670℃, ā, ko te mātotoru tūturu he 2.35g/cm3. Ka taea e te pereki ahi ātete-kirika te mahi i roto i te pāmahana teitei mō te wā roa, ā, ka mau tonu te pumau o te rōrahi me te kore e huri. Kei roto i te pereki ātete-kirika neke atu i te 94% te ihirangi SiO2. He kaha teitei te pāmahana o te pereki ātete-kirika, ā, he iti te ātete ki te ru wera. He mea hanga te pereki ahi ātete-kirika mai i te konganuku ā-kirika tūturu hei rauemi mata, kua tāpirihia he kohuke pai hei whakatairanga i te quartz i roto i te tinana matomato ka huri hei tridymite, ā, ka tahuna mārire mā roto i te pāmahana 1350~1430℃ i roto i te hau whakaiti. Ina wera ki te 1450℃, ka 1.5~2.2% o te whānui katoa o te rōrahi. Mā tēnei whānui-muri ka hiritia te hononga-tapahi, ā, ka whakarite kia mau tonu te ātete-hau me te kaha o te hanganga.
Ngā Āhuatanga o te Pereki Ahi Hiraka
- He ātete pai ki te horo waikawa,
- Te kaha o te pāmahana teitei,
- Teitei o te ātete: 1690~1710°C,
- Teitei RUL: tata ki te 1620-1670℃,
- Te pumau o te rōrahi i te pāmahana teitei,
- He ātete pai ki ngā ru wera.
Te Hanganga o te Pereki Ahi Hiraka
He pereki ātete-waihanga te poraka ahi silicon, he nui ake te ihirangi silica i te 93%, 50%-80% o te tridymite, 10%-30% o te cristobalite, te kuata me te wāhanga karāhe, tata ki te 5%-15%. Ko te hanganga mineralogi o te pereki silicate he kuata me te kuata tauine te nuinga, me te iti o te kuata me te karaihe. Ka nui te rerekētanga o te rōrahi o te kuata tauine, te kuata quartzite me te kuata toenga nā te huringa o te āhua tioata i te pāmahana iti, nō reira he ngoikore te pumau wera o te pereki ātete-waihanga silicate i te pāmahana iti. I te tukanga whakamahinga, i raro i te 800 ℃ hei whakaroa i te whakamahana me te whakamatao, kia kore ai e pakaru. Nō reira kaua e waiho i raro i te 800 ℃ te peke pāmahana o te oumu.
Te Tukanga Hanga Pereki Ahi Hiraka
He mea hanga ngā pereki ahi silicate mai i te quartzite me te iti o te matū whakakoi. Ina tahuna i te pāmahana teitei, ko te hanganga kohuke o ngā pereki ātete silicate he quartz tauine, he quartz quartz, he karāhe me ētahi atu kiko āhua matatini i hangaia i te pāmahana teitei, ā, neke atu i te 93% te nui o te AiO2 i roto i ngā pereki silicate pai ake te tahuna, ko te nui o te quartz tauine te mea teitei rawa, e 50%~80% te nui. Ko te cristobalit te mea i muri mai, e 10% ki te 30% anake te nui. Ka rerekē te nui o te quartz me te āhua karāhe i waenga i te 5% me te 15%.

Te Whakamahinga o te Pereki Ahi Hiraka
Ko ngā pereki ahi hiraka e whakamahia whānuitia ana hei rauemi ātete ahi mō te pakitara tiaki o te rūma tunu me te oumu tahu i roto i te oumu kōka, te rūma whakaora me te pute para i roto i te oumu tuwhera-ahi hanga maitai, te oumu rua me te oumu rewa karāhe, me ētahi atu wāhi pikau taumaha me te tihi i roto i te oumu tahu uku. Ka taea hoki te whakamahi i ngā pereki hiraka mō te wāhi pikau taumaha i te pāmahana teitei me te tihi o te oumu tuwhera waikawa.
