Potassium Aluminum Fluoride (KAlF4) is a commercial grade fused solid, inorganic salt. The material serves as an alternative to conventional fluoride salts for a variety of applications, a few of which are listed below.
The size can be:1-3mm, 20, 40, 100, 200 and 325mesh. It is composed by KF-AlF3, Molecular rate near 1.2, melting point 557-580. Solubility in 1000g water: at 0: 0.8g; at 25: 1.42g, at 100: 4.58g.
Packing
In 25kgs plastic woven bag lined with high-pressure plastic film, or according to customer's requirements.
Application
1. It is used directly in magnesium rich aluminium alloys to remove and control of magnesium in the aluminium alloys.
2. It is 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.
