Chemische Eigenschaften
Off-white powder. Insoluble in water and acids.
Verwenden
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.
Hazard
An irritant.
Sicherheitsprofil
Low toxicity by
ingestion. See FLUORIDES and CERIUM
COMPOUNDS. When heated to
decomposition it emits toxic fumes of F-.
