Qısa məlumat

Ge4As14Se82, Ge4As14S2Se80, Ge7As16S5Se72, Ge10As20S10Se60, Ge17.5As15S15Se52.5, Ge24As19S20Se37, Ge25As10S25Se40, Ge26As18S30Se26, and Ge33As17S35Se15 chalcogenide glass compositions were synthesized and molar percentage of element have been determined by energy-dispersive X-ray analysis. The parameters study the local structure (d, L), characterizing the chemical regularity (R) and glassy network topology (Nco, f), the glass-forming ability (Hr), the thermal stability (HMODIFIER LETTER PRIME, S), the glass and crystallization regions (Delta Tg-c) of substances corresponding to different topological glass states (isostatic, rigid, elastic) are determined and physical features of the change of these parameters depending on the composition were studied according to X-ray diffraction, differential scanning calorimetry methods and Tanaka's two-dimensional layered structure approach.
