Quartz isku qasan
Soosaarka Si iyo FeSi, isha ugu weyn ee Si waa SiO2, oo ah qaab quartz ah. Falcelinta SiO2 waxay dhalisaa gaaska SiO oo si dheeraad ah ula falgala SiC ilaa Si. Inta lagu jiro kuleyliyaha, quartz waxay u bedeli doontaa wax ka beddelka SiO2 kale oo leh cristobalite oo ah wejiga heerkul sare oo deggan. U beddelka crristo...Sii akhri -
Saamaynta macdanta macdanta ee sifooyinka alaabta dhoobada ah
Magnesium aluminium spinel (MgAl2O, MgO · Al2Oor MA) waxay leedahay sifooyin heerkul sare oo heerkul sare ah, iska caabin heer sare ah iyo iska caabin daxalka. Waa dhoobada heerkulka ugu sarreeya ee caadiga ah ee nidaamka Al2O-MgO. Kobaca doorbida ee calcium hexaluminate (CaAl12O19, CaO·6AlO...Sii akhri -
Haddii qashinka saafiga ah ee electroceramics loo isticmaali karo in lagu sameeyo dhoobada mullite?
Qaar ka mid ah qashinka warshadaha ayaa lagu muujiyay inay faa'iido u leeyihiin soo saarista dhoobada dhoobada ah. Qashinka warshaduhu waxay qani ku yihiin qaar ka mid ah oksaydhyada birta sida silica (SiO2) iyo alumina (Al2O3). Tani waxay siinaysaa qashinka suurtagalka ah in loo isticmaalo ilo bilow ah oo loogu talagalay diyaarinta dhoobada mullite. p..Sii akhri
