The viscosities of Agx[(GeS2)50(Sb2S3)50]100-x glasses and undercooled melts for x = 5, 7.5, and 15 are studied in the range of 10E6–10E13 Pa·s. The measurements are recorded using a thermomechanical analyzer and two experimental setups, the parallel-plate and penetration methods. The structural relaxation of the composition Ag10[(GeS2)50(Sb2S3)50]90 is studied using differential scanning calorimetry and thermomechanical analysis. The enthalpy and volume relaxation are characterized and described using the Tool-Narayanaswamy-Moynihan (TNM) model. It is verified that both the enthalpy and volume relaxation can be described using similar values of the TNM model parameters. The parameters characterizing the viscous flow and structural relaxation, and their relationship, are discussed. |

Viskozita Agx[(GeS2)50(Sb2S3)50]100-x skla a podchlazené taveniny pro x = 5, 7.5, a 15 byla studována v rozsahu hodnot 10E6–10E13 Pa·s. Měření bylo provedeno pomocí termomechanického analyzátoru a dvou experimentálních uspořádání, metody paralelních desek a penetrační metody. Strukturní relaxace pro složení Ag10[(GeS2)50(Sb2S3)50]90 byla studována pomocí diferenční skenovací kalorimetrie a termomechanického analyzátoru. Entalpická a objemová relaxace byla popsána pomocí TNM modelu, kde jsou získané parametry pro obě metody podobné a je diskutován vztah mezi těmito parametry a popisem viskozitního chování. |
