High-purity Cerium(III) Fluoride (CeF3, CAS 7758-88-5), 3N–5N, supplied wholesale by Zyntex. Rare earth fluoride for optical coatings, scintillator crystals, carbon arc electrodes and fluoride glasses. CoA and SDS.
Cerium(III) fluoride (CeF3) is a white powder that does not dissolve in water. It has a refractive index of about 1.63 and transmits well from the ultraviolet to the infrared.
Optical coating producers evaporate it to form durable layers in antireflection and filter coatings. Single crystals of CeF3 are fast, dense scintillators used in high-energy physics detectors. It is also a traditional additive in carbon arc electrodes for bright light sources and is used in fluoride glasses and as a polishing component.

⚠️ Safety & Handling: Harmful if swallowed or inhaled and may irritate the skin, eyes and respiratory tract; contact with strong acids releases hydrogen fluoride. Avoid dust formation and wear gloves, eye protection and dust protection. Store in tightly closed containers in a dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Which forms do you supply?
Powder and evaporation granules or pieces for coating are available. Please state form and purity when requesting a quote.
Which purity do I need for optical coatings?
Optical coatings usually use 99.9% to 99.99% material in granular form. Scintillator growth requires the highest purity.
