Ghahremanzadeh Department of Ceramic, Materials and Energy Research Center, Karaj, Iran S. Tabean Department of Ceramic, Materials and Energy Research Center, Karaj, Iran Journal Article 2014 12 03 BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperature decreases with 4% wt K2O + 4% wt B2O3 and 2% wt B2O3amount of additivesbesides condensation starts from 850 ºC.Glass-ceramics containing 4% wtK2O + 4% wtB2O3exhibitedmore sinterability in comparison with2% wtB2O3glass ceramics. SEM micrograph of glass and glass ceramic samples depicted morphology of serrated phase and hexacelsian respectively. https://www.acerp.ir/article_70005_65c8d0861c6fd015908867259c63cc91.pdf
