Structure and properties of lead-yttrium phosphate glasses
Original language description
Phosphate glasses of the system (40-x)PbO-xY2O3-60P2O5 were prepared and studied. It was found that yttrium oxide is able to form glasses with the composition (40-x)PbO-xY2O3-60P2O5 in only a narrow concentration range of 0-15 mol% Y2O3, nevertheless thereplacement of PbO by Y2O3 leads to often significant changes in the physicochemical and thermal behaviour of these glasses. TD and DSC measurements showed that the incorporation of Y3+ ions into the structural network of the lead phosphate glasses results in an increase of the glass transition temperature and the crystallization temperature. The observed differences in the glass transition temperature indicate an increase in bonding strength with increasing Y2O3 content. Raman spectra indicated that the structural network of the glasses is formed mainly from metaphosphate structural units Q2. The addition of Y3+ ions into the structural network causes partial disproportionation of the phosphate groups according to 2Q2 RIGHTWARDS ARROW
