Some aspects of glass formation in R′2O−P2O5 and R″O−P2O5 systems

Science For Glass Production


The limits of the glass-formation regions are established for the binary R′2−P2O5 and R″O5−P2O5 systems (R′=Li, Na, K: R″=Mg, Ca, Sr, Ba). It is shown that these boundaries closely correlate with those reported by other investigators despite the difference in the conditions in which these binary phosphate glasses were synthesized. The fact that all of the systems under study have about the same upper limits of glass-formation regions is attributed to the ratio R′2O(R′O): P2O5, which for the systems in question is 1.0–1.5 rather than the individual crystal-chemical characteristics of the R+ and R2+ cations.
