Properties：Sodium hexafluorophosphate is a white crystalline powder. It is highly deliquescent and readily soluble in water. It can also dissolve in low-concentration methanol, ethanol, propanol, acetone, and carbonate-based organic solvents. Density: 2.369 g/cm³, Melting point: 200°C. When exposed to air or heated, this substance decomposes very easily. Due to the effect of water vapor, it decomposes rapidly, releasing PF5 and generating white smoke, which is corrosive to the eyes, skin, and especially the lungs.。

Uses：Sodium hexafluorophosphate is mainly used as the electrolyte in sodium-ion batteries, and it features excellent ionic conductivity and electrochemical stability.

Storage：This product should be stored in a dry, cool and ventilated place. The recommended storage temperature is 10~25℃. The shelf life is 6 months.

Packing：The product shall be packed in a stainless steel container with quick connections (and protected by high purity nitrogen.) Net weight 150kg/drum.
