Cerium(III) Fluoride Structural

What is Cerium(III) Fluoride?

Chemical properties

Off-white powder. Insoluble in water and acids.

The Uses of Cerium(III) Fluoride

Cerium(III) fluoride is used to make Lewis acid. It is considered to be the most effective glass polishing agent for high precision optical polishing. Cerium fluoride used as a core additive to improve the properties of the eventual weld. The fluoride provides stability to the arc and also modifies the behavior of the molten metal flowing into the weld.

The Uses of Cerium(III) Fluoride

In arc carbons to increase their brilliance; prepa- ration of cerium metal.

Hazard

An irritant.

Flammability and Explosibility

Non flammable

Safety Profile

Low toxicity by ingestion. See FLUORIDES and CERIUM COMPOUNDS. When heated to decomposition it emits toxic fumes of F-.
