Thermal properties and crystallization of PbO-MoO3-P2O5 glasses

Popis výsledku v původním jazyce

Thermal properties and crystallization of glasses from PbO-MoO3-P2O5 ternary system were studied in three compositional series (100-x)[0.5PbO-0.5P2O5]-xMoO3 (A), 50PbO-yMoO3-(50-y)P2O5 (B), and (50-z)PbO-zMoO3-50P2O5 (C). Glass transition temperature, crystallization temperature, coefficient of thermal expansion,and dilatation softening temperature of the studied glasses were determined by differential thermal analysis and dilatometry. Crystallization products of annealed glass samples were investigatedby X-ray diffraction and Raman spectroscopy. XRD of crystallized glasses revealed the formation of PbP2O6, Pb3P4O13, and PbMoO4 in the samples of the B series. In the series A and C in the samples with a high MoO3 content, crystalline compounds of Pb(MoO2)2(PO4)2 and (MoO2)(PO3)2, respectively, were identified. Raman spectra confirmed the results of XRD and provided also information on thermal stability of glasses and formation of glass-crystalline phases. in the studied glass series.
