Zinc fluoride

Zinc fluoride (CAS 7783-49-5) is an inorganic salt used industrially as a flux agent, surface treatment chemical, and catalytic component.

Where is Zinc fluoride used?

• Metal surface treatment and electroplating: bath additive improving coating adhesion and deposit uniformity on steel and aluminum
• Semiconductor and electronics: etching formulations and precursor in thin-film deposition
• Specialty glass and optical coatings: flux that lowers melting points and modifies refractive properties for lenses and screens
• Mining and mineral processing: flotation modifier adjusting surface chemistry to improve separation efficiency
• It delivers fluoride ion activity in controlled metallurgical and electrochemical processes.

Good to know: The anhydrous form is preferred where moisture sensitivity in downstream processing is a concern. High-purity grades are available for electronics and optical applications where trace metal limits are controlled.

Commercial specifications

• Technical grade: purity typically 98% or higher
