Název v původním jazyce
Thermal properties and structure of (As2S3)100-X(Sb4S4)X glassy system
Popis výsledku v původním jazyce
Thermal properties and structure of bulk glasses of (As2S3)1-x(Sb4S4)x system (x varies from 0 up to 60) were studied by differential scanning calorimetry and Raman spectroscopy. It was found that with increasing Sb content the glasses can be sorted outto the three groups. The structure of glasses with x { 10 is build up mainly from AsS3/2 units and the well known crystallization resistance of As2S3 can explain the reluctance of these supercooled liquids against crystallization. In glasses with a higher content of antimony 10 { x { 30, the vibration characteristics of As4S4 clusters appear. Supercooled melts of these glasses crystallize to form ?-As4S4 and high-temperature phase of Sb2S3. Properties of glasses with the highest antimony content are preferably determined by SbS3/2 structural units and Sb2S3 crystallizes from their undercooled melts. Set of Raman spectra were analyzed by chemometric methods. Using Principal component analysis (PCA) and Multivariate curve resolution (MCR)
