Nō te pereki waro silicate te pereki ātete koretake, e ātete ana ki te horo o ngā para waikawa me te kawakore, ngā whakarewa, me ētahi atu waikura matū. He kaha te kaha o te kawakore silicate, he ātete pai ki te waikura, ā, kāore e huri i te pāmahana teitei. I roto i ngā rauemi mata katoa o ngā pereki ātete kore-waikura, ko te pereki waro slilica te mea tino ohanga me te nuinga o te whakamahinga i ētahi wāhi. Ka taea te whakamahi i roto i ngā ahumahi rerekē, pērā i te ahumahi kōhatu, te ahumahi karāhe, te ahumahi whakarewa, te ahumahi tā, me te ahumahi mārama. Haunga tēnā, he tino pai te mahi a te pereki waro silica ki te ātete ki te horo kino o te taiao, pērā i te kawe wera nui, te ātete pai ki te karawarawa, te ātete nui ki te ru wera, te ātete kaha ki te horo o te para waikawa me te kawakore me te tauwehenga whakawhānui wera iti me ētahi atu.
Ngā Āhuatanga o te Pereki Karāpi Hiraka
- Te kaha teitei,
- Te kawe wera teitei,
- He ātete pai ki te whakakoi,
- He ātete nui ki te ru wera,
- He tino ātete ki te horo,
- He kaha te ātete ki te horo o te para waikawa me te kawakore,
- He iti te tauwehenga whānui o te wera.
Te Hanganga o te Pereki Karapire Hiraka
Ko ngā rauemi mata o te poraka karāhe silicate he karāhe silicon, tata ki te 72%-99%. E kiia ana hoki te karāhe silicon ko te moissanite, te onepu corundum, te onepu ātete rānei. He mea hanga tēnei mā te onepu quartz, te coke hinu, te tāra waro rānei, me ngā wahi rakau, e whakaputaina ana mā te whakarewa pāmahana teitei i roto i te oumu ātete hiko.
Te Tukanga Hanga Pereki Hiraka Carbide
Ka hangaia ngā pereki silicon carbide mai i te silicon carbide, he rauemi mata i hangaia i roto i te oumu hiko momo-ātete i te pāmahana neke atu i te 2500°C, mā te tauhohenga o te silica ki te waro. Tekau ngā wā ka taea e ngā pereki silcate te kawe wera atu i ngā pereki fireclay, he pai te ātete ki te waikura me te ru wera, ā, ka taea te hanga hei āhua uaua. Ka taea e ngā pereki silica cabon te tu atu i te whakaekenga para me te mimiti mura.
Te Whakarōpūtanga o ngā Pereki Karapiti Hiraka
Ka taea te whakarōpū i ngā pereki ātete warowaihā konukōre ki te uku, ki ngā pereki warowaihā konukōre ki te Si3N4, ki ngā pereki warowaihā konukōre ki te Sialon, ki ngā pereki warowaihā konukōre ki te β-SiC, ki ngā pereki warowaihā konukōre ki te Si2ON2 me ngā pereki warowaihā konukōre ki te karaihe anō.

Te Whakamahinga o te Pereki Karāpi Hiraka
He nui te kawe wera o te pereki waro silica, he pai te ātete ki te kakahu, te ātete ki ngā ru wera me te ātete ki te waikura. Nō reira, he whānuitia ngā whakamahinga o ngā pereki waro silica:
- Oumu uku,
- Te whakapuru o te zincretort,
- Te arai o te pūtau konumohe,
- He ara iahiko ngongo konumohe whakarewa,
- Omu pupuhi nui me te oumu waenga,
- Te arai o te oumu o te oumu whakapara konumohe.
