By the use of a mixture of alkali cations, Li, Na, and K, it has been possible to prepare phosphate glasses with higher M 2 O/P 2 O 5 , ratio than was possible by the use of a single alkali cation. Variation of the Na:K ratio over a wide range has no effect on the distribution of polyphosphates in the composition range studied (Li: Na: K = 1:5:1 to 1:1:5). Glasses with × values of 2 or less contain an appreciable amount of orthophosphate ion. The significance of these results is discussed.
