Rare-earth trifluoride with new morphological characteristics, and its preparation process |
| abstract |
The present invention relates to a rare earth trifluoride with new morphological characteristics. It also relates to the process for obtaining said fluoride which is characterized in that an aqueous solution of rare earth salt is reacted with an ammonium fluoride solution, that the precipitate formed is separated and that it is subjected to a heat treatment. The rare earth fluoride of the invention has a fine and monodisperse particle size distribution. |
