    • Phosphorus pentoxide (P2O5)

      Phosphorus pentoxide is a white, microcrystalline, light weight powder which is produced by the combustion of elemental phosphorus in an excess of oxygen. Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. It is very hygroscopic and is converted by water to H3PO4 via intermediates. The reaction with water is very vigorous and proceeds with the evolution of a large amount of heat. Due to its highly hygroscopic and microcrystalline character, the capability of flowing of P2O5 may vary in a certain range. Furthermore, the formation of soft agglomerates, which come apart under slight pressure, is not preventable.   more

    • Polyphosphoric acid 84%

      Polyphosphoric acids are odourless, high viscousity liquids with strongly hygroscopic properties. Phosphoric acids with <95 % H3PO4 (68 % P2O5) contain the simple orthophosphoric acid. At higher concentrations the acid consists of a mixture of ortho, pyro, tri, tetra and highly condensed phosphoric acids. For this reason acids with a concentration > 68 % P2O5 are commonly known as polyphosphoric acids. Polyphosphoric acids are miscible with water, hydrolysing to orthophosphoric acid with the generation of heat. They are insoluble in hydrocarbons and halogenated hydrocarbons. more
