Low-temperature heat capacity and thermodynamic properties of silicon-dioxide-based binary vitreous systems
The concentration and temperature dependences of the heat capacities of vitreous SiO2Al2O3 and SiO2TiO2 systems are studied. The heat‐capacity behaviour of the glasses studied in the range from 5 to 300 K is shown to be described satisfactorily by combinations of the Debye and Einstein heat‐capaci...

description | The concentration and temperature dependences of the heat capacities of vitreous SiO2Al2O3 and SiO2TiO2 systems are studied. The heat‐capacity behaviour of the glasses studied in the range from 5 to 300 K is shown to be described satisfactorily by combinations of the Debye and Einstein heat‐capacity functions. It is established that the isotherms of the concentration dependences of heat capacity are of a nonmontonic nature. The dynamic characteristics of a vibrational spectrum and the basis thermodynamic functions of glasses of the SiO2Al2O3 and SiO2TiO2 systems are calculated on the basis of precise calorimetric measurements.
Es werden die Konzentrations‐ und Temperaturabhängigkeiten der Wärmekapazitäten von glasartigen SiO2Al2O3‐ und SiO2TiO2‐Systemen untersucht. Das Wärmekapazitätsverhalten der untersuchten Gläser im Bereich von 5 bis 300 K wird befriedigend beschrieben durch Kombinationen der Debye‐ und Einstein‐Wärmekapazitätsfunktionen. Es wird gesichert, daß die Isothermen der Konzentrationsabhängigkeiten der Wärmekapazität nichtmonoton sind. Die dynamischen Charakteristiken des Schwingungsspektrums und die thermodynamischen Grundfunktionen der Gläser der SiO2Al2O3‐ und SiO2TiO2‐Systeme werden auf der Grundlage von genauen kalorimetrischen Messungen berechnet. |
