Study of structure and properties of ZnO-Bi2O3-P2O5 glasses

Original language description

Glasses of the ternary system ZnO-Bi2O3-P2O5 were prepared and studied in two compositional series 50ZnO-xBi2O3-(50-x)P2O5 and (50-y)ZnO-yBi2O3-50P2O5. Two distinct glass-forming regions were found in the 50ZnO-xBi2O3-(50-x)P2O5 glass series with x = 0-10 and 20-35 mol% Bi2O3. All prepared Bi2O3-containing glasses reveal a high chemical durability. Small additions of Bi2O3 (~5 mol%) improve thermal stability of glasses. All glasses crystallize on heating within the temperature range of 505-583oC. Structural studies by Raman and 31P MAS NMR spectroscopies showed the rapid depolymerisation of phosphate chains within the first region with x = 0-15 and the presence of isolated Q0 phosphate units within the second region with x = 20-35. Raman studies showedthat bismuth is incorporated in the glass structure in BiO6 units and their vibrational bands were observed within the spectral region of 350-700 cm-1. The evolution of properties and the spectroscopic data are both in accordance with a

Studium struktury a vlastností skel systému ZnO-Bi2O3-P2O5

Czech description

Byla studována struktura a vlastnsoti skel systému ZnO-Bi2O3-P2O5 připravých ve dvou kompozičních řadách: 50ZnO-xBi2O3-(50-x)P2O5 a (50-y)ZnO-yBi2O3-50P2O5. Malé přídavky Bi2O3 (~5 mol%) zvyšují termickou stabilitu skel. Všechna skla při zahřívání v teplotním intervalu 505-583oC. Strukturní studie skel ukazují na rychlou depolymerizaci fosfátových řetězců s rostoucím obsahem Bi2O3.
