Reliable, with one-point correction of energy scale
Comment:
The sample was prepared from Al(PO3)3, NaPO3, Li2CO3, K2CO3, ZnO, SnO, and NH4H2PO4 batch materials which were melted at 1273 K for 3 h and annealed at 573 K. The intensity ratio of the non-bridging/bridging oxygen components was 80.4/19.6.
