Yttrium phosphate is an inorganic chemical compound of yttrium from the group of phosphates .

Occurrence

Yttrium phosphate occurs naturally in the form of the mineral xenotime and as a dihydrate as a Weinschenkit .

Extraction and presentation

Yttrium phosphate can be obtained by reacting yttrium (III) chloride with sodium phosphate at 200–1000 ° C or by reacting yttrium (III) nitrate with ammonium dihydrogen phosphate .

It is also possible to produce it by reacting yttrium oxide with diammonium hydrogen phosphate .

properties

Yttrium phosphate is a colorless solid that is partially soluble in phosphoric acid and slightly soluble in water. It has a crystal structure isotypic to that of zircon .

use

Yttrium phosphate is used as a catalyst and is a possible containment material for nuclear waste. Yttrium phosphate doped with cerium or bismuth shows luminescence in the UV range and can be used for tanning lamps.
