Syrup-like solution, solid transparent crystal. Pyrophosphate hygroscopicity. Solid pyrophosphate is formed by the spontaneous crystallization of a mixture of polyphosphoric acids with a P2O5 content of 79.8% ± 0.2%. Soluble in ethanol, ether. When heated to above the melting point, it decomposes into a liquid acid containing orthophosphoric acid, pyrophosphoric acid, trimetaphosphoric acid, polymetaphosphoric acid and the like. Crystalline pyrophosphate in ice water is not too decomposition, but decomposition at high temperatures, the amount of orthophosphate increased.


As a catalyst, metal refining, organic peroxides of the stabilizer. Used in the electroplating process to adjust the electroplating solution of Ph value of Ph, also used for other plating.

Storage: Storage should be cool and ventilated, away from heat, fire, to prevent sun exposure, heat is strictly prohibited.
