Lithium Hexafluorophosphate (LiPF6), low moisture; high purity
Description
Lithium Hexafluorophosphate and Lithium Tetrafluoborate are the
preferred electrolyte salts for lithium batteries. Our highly pure
grades of LiPF6 and LiBF4
have the characteristics, that is, low free acid and low insoluble.
The bottle is covered with Al-laminated sheet to keep the characteristics.

3. Material Handling Precautions
Both LiPF6 and LiBF4 should
be handled in a dry environment. Local exhaust ventilation should
be provided when handling the products in order to control the release
of contaminants into the air. These salts are extremely hygroscopic
and LiPF6 may evolve volatile fluorides such
as POF3 and HF as products of decomposition
if allowed to be in contact with moisture.
