Potassium fluoride is a white powder with high activity and deliquescence.
The bulk density is 0.35 and the relative density is 2.48.
The melting point is 858 ° C and the boiling point is 1505 ° C.
Refractive index 1.363.
Soluble in water, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone.
The aqueous solution is alkaline and can corrode glass and porcelain.
The product is used for glass engraving, food preservation, electroplating.
It can be used as welding flux, insecticide, fluorinator of organic compounds, catalyst, absorbent, etc.
It is also a raw material for the preparation of potassium hydrogen fluoride.
At present, as an intermediate, it is widely used in medicine, pesticide and other industries, and its excellent performance is manifested in high activity, high yield, low dosage and low by-product of fluorination reaction.
Secondly, expensive phase transfer catalysts do not need to be used for fluorination.
