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.
