Ko te pereki whakaraerae o te Silica he whakaahuru waikawa, he pai hoki te aukati i te horo o te parae waikawa. Slica pereki refractoriness i raro i te kawenga he ki runga ki te 1640 ~ 1690 ℃, kitea tuatahi pāmahana ngohengohe ko 1620 ~ 1670 ℃ me te kiato pono ko 2.35g/cm3. Ka taea e te pereki ahi Silicon te mahi i roto i te pāmahana teitei mo te wa roa me te pupuri i te pumau o te rōrahi kaore he huringa. Ko te pereki reractory Silicon kei runga i te 94% te ihirangi SiO2. He pai ake te kaha o te pāmahana teitei o te pereki silicate, me te iti o te awangawanga waiariki. Ko te pereki ahi silicate he mea hanga mai i te silica ore taiao hei rauemi mata, ka taapirihia he kohuke e tika ana hei whakatairanga i te kiripaka i roto i te tinana matomato ka huri hei tridymite me te puhipuhi puhoi ma te mahana o te 1350 ~ 1430 ℃ hei whakaiti i te hau. A, no te wera ake ki te 1450 ℃, reira pūkete 1.5~2.2% o te roha rōrahi katoa. Ma tenei whakawhanui-a-muri ka hiri te tapahi-tahi me te whakarite kia mau te hangai i te hau koretake me te kaha o te hanganga.
Ko te poraka ahi Silicon he pereki whakaahuru e nui atu i te 93% te ihirangi silica, 50% -80% o te tridymite, 10% -30% o te cristobalite, te kiripaka me te wahanga karaihe, mo te 5% -15%. Ko te hanganga kohuke o te pereki silicate te nuinga o te quartz me te quartz, me te iti o te quartz me te vitreous. Ko te quartz tauine, te quartz quartzite me te toenga o te kiripaka ka rerekee i te rōrahi na te huringa o te ahua karaihe i te iti o te pāmahana, na reira he kino te whakamaarama waiariki o te pereki refractory silicate i te pāmahana iti. I roto i te tukanga whakamahi, i raro i 800 ℃ ki puhoi whakawera me te meangiti, kia rite ki te karo kapiti. No reira, kaua e iti iho i te 800 ℃ te wera o te oumu.
Ka hangaia nga pereki ahi silicate mai i te quartzite me te iti o te kaihoko kohuke. Ka tahuna ki te wera nui, ko te tito kohuke kohuke pereki whakaahuru silica ko te quartz tauine, te quartzite quartz, te karaihe me etahi atu waahanga uaua i hangaia i te pāmahana teitei, me te ihirangi AiO2 neke atu i te 93%. I roto i nga pereki silica pai ake te pupuhi, ko te ihirangi o te quartz tauine te mea teitei, e 50% ~ 80%. Ko cristobalit i muri mai, 10% ki te 30% noa iho. Ko nga mea o roto o te kiripaka me te wahanga karaihe he rereke i waenga i te 5% ki te 15%

Ko te pereki ahi Silica te nuinga e whakamahia ana hei rauemi whakaahuru mo te taiepa whakamarumaru o te ruuma coking me te mura i roto i te oumu coke, te ruuma whakahou me te pute para i roto i te hangai i te oumu tuwhera-waahi, te oumu poka wai me te oumu whakarewa karaihe, me etahi atu waahanga taumaha me te tihi i roto i te raima. oumu pupuhi. Ka taea hoki te whakamahi i nga pereki silicate mo te waahi e mau ana i te taumaha i roto i te pāmahana teitei me te tihi o te oumu ahi tuwhera waikawa.
