Study of crystallization of PbO-WO3-P2O5 glasses by thermoanalytical and spectroscopic method

Popis výsledku v původním jazyce

The crystallization of PbO-WO3-P2O5 ternary glasses was studied in three compositional series of (100 x) [0.5PbO-0.5P(2)O(5)]-xWO(3) glasses (A series), 50PbO-(50 - y)P2O5-yWO(3) glasses (B series) and (50 - z) PbO-50P(2)O(5)-zWO(3) glasses (C series) beginning with Pb(PO3)(2). The crystallization products of the annealed glass powders were evaluated using X-ray diffraction and Raman spectroscopy. The results of the X-ray diffraction analysis of the crystallized glasses revealed the formation of severalcrystalline phosphate compounds and in the samples with a high WO3 content also the formation of a new crystalline compound of Pb(WO2)(2)(PO4)(2) in series A and B. From the obtained diffraction pattern, the hexagonal cell parameters were calculated asa = 11.3531(1) angstrom and c = 63168(1) angstrom. The surface mechanism of crystallization dominates the crystallization process of the glass into the Pb(WO2)(2)(PO4)(2) compound as evaluated using Day's method. Raman spectra of the crys
