[Character] Density is 2.55. Fused - matter will be decomposed of phosphorus pentafluoride and potassium fluoride slowly at 515 ℃. Its solubility in water :3.65 g/100ml ( 0℃), 8.35 g/ 100ml(25℃), 38.3 g / 100ml(100℃). It can't be decomposed in water when PH isn't less than three.

[Uses] Used for manufacturing photosensitive dope and electrolyte, and used to compose of some biology preparation, and compose of other hexafluorophosphate salts in place of hexafluorophosphate acid.

[Packing] Packing with pasteboard barrel or iron barrel lined with polythene plastic bag. 25kg or 50kg per barrel.
