Product Description

Potassium Hydrogen Fluoride with CAS 7789-29-9

Potassium hydrogen fluoride is a chemical substance, a colorless crystal. Slightly sour. The melting point of about 238 ℃ (decomposition). Soluble in water, not in ethanol. The aqueous solution is acidic. Don't decompose release hydrogen fluoride in dry air, absorb the moisture release hydrogen fluoride in the moist air, heated to 310 ℃ have hf escape, to 400 ℃ hydrogen fluoride vapor pressure of 0.101325 MPa (1 ATM). The activity of molten potassium hydrogen fluoride than potassium fluoride and sodium fluoride. Poisonous.

Storage method editing
1. Store in a cool, dry and well-ventilated warehouse.
Stay away from fire and heat. Keep the container sealed. Moisture-proof and sun-proof.
3. Separate storage with acids, edible chemical materials, etc.

1. Electrolytes for the production of anhydrous hydrogen fluoride, pure potassium fluoride and elemental fluorine.
2. Used for making optical glass and etching glass.
3. Used as welding flux for silver products, preservative for wood, masking agent and catalyst for benzene alkylation, etc.
4. Potassium fluoride can be used for matte treatment of aluminum and alloy, as well as for the etching of silicon and titanium
Amount of nitric acid or chromic anhydride to prevent hydrogen embrittlement.

In aluminium and its alloy passivation and phosphating processing is an important additive substance, used as activator of aluminium and its alloy passivation and phosphating, and to promote the formation of the passivation film and phosphating film, but high concentration can make the film layer of loose, can't even film.
