Rare Earth Fluoride

Rare earth fluorides are compounds composed of rare earth elements and fluorine atoms, usually white crystals with good thermal and chemical stability. Fluorinated rare earths have a very important position in the rare earth industry, and their main applications include electronics, catalysis, ceramics, energy and other fields.

Fluoride refers to organic or inorganic compounds containing negative fluorine. Like other halogens, fluorine forms a single negative anion (f −). Fluorine can form binary compounds with all elements except He, Ne and Ar. Rare earth fluoride refers to the compound composed of fluorine and rare earth metal elements. The common rare earth fluoride are LaF3, CeF3, PrF3, NdF3, GdF3, DyF3, YF3, etc. It can be used in biochemical research, yttrium salt, fireworks, precipitant, infrared low refractive index materials, laser crystal materials, up conversion luminescence materials and so on.

Our main products include praseodymium fluoride, neodymium fluoride, praseodymium fluoride, dysprosium fluoride, terbium fluoride, gadolinium fluoride, yttrium fluoride, holmium fluoride and etc.
