Lebenka silica refractory waa aashitada refractory waxayna leedahay caabbinta nabaadguurka aashitada. Lebenka Slica refractorness hoos load waa ilaa 1640 ~ 1690 ℃, muuqata heerkulka jilcin bilowga ah waa 1620 ~ 1670 ℃ iyo cufnaanta dhabta ah waa 2.35g/cm3. Lebenka dabka ee Silicon wuxuu u adeegi karaa heerkul sare muddo dheer wuxuuna ilaalin karaa xasilloonida mugga iyada oo aan isbeddel lahayn. Leben dib u soo celinta Silikon ka kooban yahay in ka badan 94% SiO2. Lebenka silicate wuxuu leeyahay awood heerkul sare oo heer sare ah iyo iska caabin shoog kulayleed hooseeya. Lebenka dabka silicate wuxuu ka samaysan yahay macdanta silica dabiiciga ah sida alaabta ceeriin, oo lagu daray macdanta ku habboon si kor loogu qaado quartz ee jirka cagaaran oo loo beddelo tridymite oo si tartiib tartiib ah loo shido iyada oo loo marayo heerkulka 1350 ~ 1430 ℃ yaraynta jawiga. Marka kuleylka ilaa 1450 ℃, waxaa jira 1.5 ~ 2.2% wadarta ballaarinta mugga. Balaadhintan ka dib waxay ka dhigi doontaa goynta wadajirka ah ee la shaabadeeyey waxayna hubin doontaa in dhismuhu uu hayo hawo wanaagsan oo aan nadiif ahayn iyo xoogga qaabdhismeedka.
Dab-damiska Silicon waa leben dib u celinaya in maadada silica ay ka badan tahay 93%, 50%-80% tridymite, 10%-30% of crristobalite, quartz iyo galaaska, qiyaastii 5% -15%. Halabuurka macdanta ee leben silicate waa inta badan quartz iyo quartz, iyo sidoo kale qadar yar oo quartz iyo vitreous ah. Quartz miisaan leh, quartz quartz iyo quartz haraaga ah ayaa si weyn u beddela mugga sababtoo ah isbeddelka qaabka crystal ee heerkulka hooseeya, sidaas darteed xasilloonida kuleylka ee lebenka silicate refractory ayaa liidata heerkulka hooseeya. Habka isticmaalka, ka hooseeya 800 ℃ si loo yareeyo kuleylka iyo qaboojinta, si looga fogaado dildilaaca. Markaa waa in aanu ka hoosayn 800 ℃ heerkulbeegga foornada.
Lebenka dabka silicate waxaa laga sameeyaa quartzite oo leh qadar yar oo ah wakiilka macdanta. Marka lagu gubo heerkul sare, lebenka silica refractory ee macdanta macdanta ayaa ka kooban quartz cabirka, quartzite quartz, galaas iyo unugyo kale oo adag oo lagu sameeyay heerkul sare, iyo content AiO2 waa in ka badan 93%. Ka mid ah lebennada silica ee si fiican loo shiday, nuxurka quartz miisaanku waa kan ugu sarreeya, oo xisaabiya 50% ~ 80%. crristobalit ayaa ku xigay, isaga oo ku xisaabtamaya kaliya 10% ilaa 30%. Waxa ku jira quartz iyo wejiga galaasku waxa ay is beddelaan inta u dhaxaysa 5% iyo 15%

Lebenka dabka silica waxaa inta badan loo isticmaalaa sida agabka soo celiska ah ee gidaarka ilaalinta qolka coking iyo combustor ee foornada kookaha, qolka dib-u-cusboonaysiinta iyo jeebka suufka ee foornada foornada furan ee birta samaynaysa, foornada godka lagu qooyay iyo foornada dhalaalaysa dhalada, iyo meelaha kale ee miisaanka lagu qaado iyo dusha dhoobada foorno rasaas ah. Lebenka silicate sidoo kale waxaa loo isticmaali karaa aagga miisaanka lagu qaado ee heerkulka sare iyo sare ee foornada dabka furan ee aashitada.
