Studies of Rare Earth Polyphosphate Glasses of Composition [NaxM(1-x)/2aDy(1-x)/2aPO3]n

Abstract

Fusion technique was used for the preparation of derivatives of composition
[Na_xM_(1–x)/2aDY_(1-x)/2aPO₃]_n [where M¹ = bivalent metal like Cu(II), Ca(II),
Zn(II) and Mg(II) and X = 2/3 and 3/4 and a = valency of metal]. Compositions
of these polyphosphate glasses were confirmed by their analysis for metals and
phosphorus. The polymeric nature of all polyphosphate glasses was confirmed by
determination of number average molecular weight (Mn). The characteristic
frequencies in the IR spectra are supportive of the presence of polyphosphate
indicative of the polymeric nature of these derivatives.
