Electrical Grade Phosphorus Pentoxide is used for doping to form anti-refraction in opto-electronics and optical glass; and also used for N-type doping in certain solar cell fabrication.

It can be used for Potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (DKDP) single crystal growing.

It can be used in superior quality medicine and cosmetic industries because of super low heavy metals content and also used for making high-quality Phosphoric Acid.



Phosphorus Pentoxide is a chemical compound with molecular formula P4O10. The common name is derived from its empirical formula, P2O5. It’s kind of white crystalline powder. This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.
P4O10 is prepared by burning elemental phosphorus with sufficient supply of air.
