Physicochemical Properties of Sodium Fluoride

Physical and Chemical Properties: Colorless shiny crystals or white powder, specific gravity 2.25, melting point 993°C, boiling point 1695°C. Soluble in water and hydrofluoric acid, slightly soluble in alcohol. Aqueous solution is weakly alkaline. Dissolves in hydrofluoric acid to form sodium hydrogen fluoride. Can corrode glass. Toxic!

Sodium Fluoride Standard: GB4293-84

Indicator Name: Premium Grade

Used as a phosphating accelerator in the coating industry to stabilize phosphating solutions, refine phosphating, and improve the performance of phosphating films. In the phosphating of aluminum and its alloys, it seals the highly harmful negatively catalytic Al³⁺ ions, enabling smooth phosphating. Also used as a wood preservative, agricultural insecticide, brewing industry bactericide, medical preservative, welding flux, alkaline zincate galvanizing additive, and in enamel, papermaking, etc.

Sodium Fluoride Packaging

Net weight per bag: 25KG, packaged in double-layer woven bags. Inner packaging uses polyethylene plastic film bags, outer packaging uses polypropylene plastic woven bags.

Sodium Fluoride Storage and Transportation

Store the product in a ventilated, cool place, protected from sunlight, moisture, and rain.

Sodium Fluoride Storage Applications

1. Sodium fluoride is an important fluoride salt used as an additive to electrolytes during the startup of electrolytic cells.

2. Used as an agricultural insecticide, bactericide, and raw material for cockroach powder.

3. Used in the镶钢 process of mechanical blades and planer knives to lower the镶钢 melting point and increase welding strength.

4. Used in the manufacturing of沸腾钢, light metal fluoride treatment agents, and metal fluxes.

5. Used as a wood preservative, water treatment agent, ceramic pigment, and fluoride treatment agent for drinking water.

6. Used as a UF₃ adsorbent in the nuclear industry and for the treatment of raw hides and skins in the leather industry.

7. Used as a raw material for manufacturing other fluorides, and applied in enamel, pharmaceutical industries, paper production, and building materials.
