Computer simulation of the structural and thermodynamics properties of liquid and amorphous SiO2

The temperature dependence of the structure and of some properties of liquid and amorphous SiO2, have been simulated by the Statical Relaxation and Molecular Dynamics methods. Especially, the temperature dependence of the pore distribution and the heat capacity have been obtained. The transition fro...

Zusammenfassung:The temperature dependence of the structure and of some properties of liquid and amorphous SiO2, have been simulated by the Statical Relaxation and Molecular Dynamics methods. Especially, the temperature dependence of the pore distribution and the heat capacity have been obtained. The transition from supercooled liquid to amorphous SiO2 has been determined to be a second-order phase transition around the temperature 1700 K.
