Synonyms: Sodium hydrogen difluoride; Fluoruroacidodesodio; Sodium hydrogen fluoride; SODIUM ACID FLUORIDE; SODIUM BIFLUORIDE; SODIUM DIFLUORIDE
Appearance: White pellets
Assay: a Y98%
Character: Acid salt of sodium fluoride It is a colorless or white crystal with relative density of 2.08. It has strong sourness. It is soluble in water but insoluble in alcohol. In humidity air it absorbs moisture and releases hydrogen fluoride. When heated to 160 a it decomposes into sodium fluoride and hydrogen fluoride. At high temperature aluminium and aluminium alloy can resist the corrosion of hydrogen fluoride. Its aqueous solution can etch glass. It is toxic.
Uses: It is used as aseptic of food dissection specimen as glass etchant in glass frosting for texture finishing of textile in wiping off rust in insect proof treatment of leather as the material for tinplate and to produce anhydrous HF. Its mixture with potassium hydrogen fluoride can be used as flux of metal.
Packing: Packing with plastic woven bag lined with polythene plastic bag. 25kg per bag or 25kg fiber drum.
