摘要：

A series of ceramics derived from glasses of general formula (P2O5)(0.45)(CaO)(0.2+x)(Na2O)(0.35-x) (x = 0.0-0.12) were prepared and one- and two-dimensional P-31 magic-angle spinning NMR spectroscopy confirmed the predominant speciation of Q(1) phosphorus as Na-4-, Na2Ca-, and alpha and beta-Ca-2-P2O7, but did not show any Q(1)-Q(2) connectivity characteristic of short metaphosphate chains.
