Useful:

• Description: Superphosphoric acid is made by the concentration of regular wet-process acid up to P2O5 concentrations of 78%. Granular polyphosphates suitable for bulk blending are made by reacting ammonia with regular wet process acid of 52% P2O5 content and using the heat of reaction to drive off water to produce a phosphate melt of 10-43-0, with about 40% of the phosphorus in the polyphosphate form. These materials are, however, not suitable for bulk blending due to their “sticky” nature (10).
• Uses: Dehydrating, catalytic, and sequestering agents, for metal treating; many applications where a con- centrated monooxidizing acid is needed; laboratory reagent. Polyphosphoric Acid is a ligand used as an analytical tool to image nanoparticles through photon emission topography. Used also in the synthesis of pharmaceuticals.
