PHASE EQUILIBRIUM AND GLASS FORMATION IN THE AsS-ErS SYSTEM
نویسندگان
چکیده
Phase equilibrium and glass formation between AsS ErS compounds were studied by methods of physicochemical analysis: differential-thermal (DTA), X-ray phase (XRD), microstructural analysis (MSA), as well measuring microhardness density. The T-x diagram the AsS–ErS system was constructed. It has been established that is quasi-binary, eutectic type characterized chemical compound ErAsS2. ErAsS2 formed a result peritectic reaction M+ErS↔ at 7500C crystallizes in tetragonal syngony with lattice parameters: a=13.62; c=18.93 Ǻ; ρpuc= 5.17 g/cm3, ρX-ray= 5.21 g/cm3. composition 10 mol % temperature 280oC. Under normal cooling conditions, area based on reaches ErS. For alloys, some properties have studied. Solubility up to 1.5 ErS, solubility practically not

We use computer simulations to study the thermodynamic properties of a glass-former in which a fraction c of the particles has been permanently frozen. By thermodynamic integration, we determine the Kauzmann, or ideal glass transition, temperature [Formula: see text] at which the configurational entropy vanishes. This is done without resorting to any kind of extrapolation, i.e., [Formula: see t...
