It is sodium fluoride, an inorganic substance with chemical formula of NaF, colorless and shiny crystal or white powder compound, with specific gravity of 2.25, melting point of 993℃ and boiling point of 1695℃. Soluble in water (solubility10 c3.66, 20°C 4.06, 30°C 4.22, 40°C 4.4, 60°C 4.68, 80°C 4.89,100 c5.08), hydrofluoric acid, micro.

The aqueous solution is weakly alkaline, soluble in hydrofluoric acid to form sodium hydrogen fluoride, which can corrode glass. Poisonous! Widely used in coating industry as phosphating accelerator, agricultural insecticide, sealing material, preservative and other fields.

Main uses of sodium fluoride:

Used as wood preservative, water treatment agent, ceramic pigment, boiling steel, light metal fluoride treatment agent, smelting and refining, protective layer and UF3 adsorbent in nuclear industry. In the production of sealing materials and brake pads, the wear resistance is increased. Mechanical blade planer inserts steel to increase welding strength.
