General description
Sodium phosphate glass is composed of Na2O–P2O5. It is used as a sequestering agent in hard water treatment and also as a dispersant in clay processing and pigment production. In Na-ion batteries, sodium phosphate glass can be used as a solid electrolyte.
Application
Sodium phosphate glass type 45 (polyP45) can be used as a reference material in the extraction and quantification of inorganic polyphosphate residues found in microorganisms.
Biochem/physiol Actions
Reported to be of use in protein binding and sequestering and in studies on bone calcification.
Other Notes
Nan+2PnO3n+1; n = the average number of phosphorus (P) atoms in the chain.

Some sponges have been shown to accumulate abundant phosphorus in the form of polyphosphate (polyP) granules even in waters where phosphorus is present at low concentrations. But the polyP accumulation occurring in sponges and their symbiotic bacteria have been little
