General description
Potassium tetrafluoroborate is a white crystalline salt with a low melting point. It is used as a reagent in organic synthesis, high-efficiency electrolyte additive, and in electroplating applications.
Application
Potassium tetrafluoroborate can be used as:
- An additive to perovskite precursor solution for preparing wide bandgap perovskite films for solar cells.
- An electrolyte additive in potassium ion and Li-ion batteries to enhance stability and performance.
- A reagent in the synthesis of bis-N-heterocyclic carbene (NHC) ruthenium complex.
- An electroplating solution to prepare metal coatings and alloys.
