PAF Potassium Cryolite

Product Description

 

Chemical Names: Potassium fluoroaluminate;potassium aluminium fluoride

Potassium fluoroaluminate( Potassium Cryolite)

Formula: KAlF4, K3AlF6



Properties:

 

 

 

Potassium Cryolite is a complex fluoride salt of potassium and aluminium. It does not have a specific chemical formulae. It is a mixture of following salts:

 

 

 
  1. K3AlF6
  2. K2AlF5
  3. KAlF4
 

 

 

Potassium Aluminum Fluoride is one of the primary constituent in salt fluxes for metal cleaning, combined with other chloride and sulphate salts such as NaCl . The addition of fluoride aslts enhances the performance of the salt flux. These salt flux help in separation of metals from their oxides and dross and prevents further burning of the molter aluminum, therefore increasing its yield. 

 



Application: 

1. Potassium Cryolite is also used directly in magnesium rich aluminium alloys to remove and control of magnesium in the aluminium alloys. It is much safer in this applications where earlier Chlorine gas or HEXACHLOROETHANE were used, these gases cause local health problems and are also responsible for ozone depletion.  


2.Potassium Cryolite is also used in the manufacture of grinding wheels (filler/binder) and other abrasive products. 



3.Other common applications of PAF are as additive to roofing shingles, where it acts as an alkaline Ph adjuster and flame retardant. It can also be used as color additive to the coatings for roofing granules.

4.Glass producers use the PAF for opacification, or to cloud the glass giving it a milky white color. 
Packing: in 25kg/50kg/1000kg plastic woven bags
