98% Min KBF4 Crystalline Powder Fluoride Salt for Aluminium Metallurgy

98% Min KBF4 Crystalline Powder Fluoride Salt for Aluminium Metallurgy

 
►Decription
 
   Potassium Fluoroborate is a  white  gelatiniform crystal or powder ,
 
nonhygroscopic and bittering. It is a hexagonal rhombus crystal when crystalized
 
from aqueous solution. Its relative density is 2.505, mp 530°c . It is slightly soluble
 
in water and hot ethanol. It decomposes at melting point, reacts with strong acids
 
such as sulfuric acid to produce boron trifluoride, reacts with alkaline metal
 
carbonates to produce fluoride and borate. It is toxic!

►Specification 

►Application 
 
1 Aluminium-metallurgy: as component in fluxing and grain refining agents
 
for aluminium and magnesium as component in protecting salts for light metal
 
castings.
 
2 Production of abrasives:as active filler in resin-bonded abrasives for metal
 
treatment.
