Öğe Glass formation in Li2O?Pr2O3?B2O3 system(Selçuk Üniversitesi Mühendislik-Mimarlık Fakültesi, 2008) Hamidova, Sh. A.; Novruzova, F. A.; Agapashayeva, S. M.By methods of physical?chemical analysis (DTA, X?ray diffraction, IR?spectroscopy) phaseand glass formation in Li2O?Pr2O3?B2O3 system was researched in zone, which is enriched with boric anhydride. According to the results of three quasi binary sections: Li2O?3B2O3? Pr2O3?3B2O3; Li2O?2B2O3? Pr2O3?3B2O3; Li2O?2B2O3? Pr2O3?B2O3, as well as materials about glass formation in binary Li2O?B2O3? and Pr2O3?B2O3 systems the zone of glass formation and glass transition diagram of Li2O?Pr2O3?B2O3 was defined.Öğe Triple system Ge-Sm-Te(Selçuk Üniversitesi Mühendislik-Mimarlık Fakültesi, 2007) Mukhtarova, Z. M.; Bakhtiyarly, I. B.; Ajdarova, D. S.; Novruzova, F. A.By methods of physical-chemical analysis the surface projection of liquidus of triple system Ge-Sm-Te was plotted on base of investigated internal sections: GeTe-Sm2Se3, SmTe-Sm5Ge3, GeTe-SmTe, Ge080Te020- Sm080Te020, Ge080Te026- Sm5Ge2Te7. The peritectic compound Sm5Ge2Te7 was found in triple system. Crystallization fields of phases were determined, and coordinates of nonvariant points, as well as the reaction, which proceeds in triple system Ge-Sm-Te, was defined.
