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!
