Lutetium phosphate is an inorganic compound, a salt of lutetium and phosphoric acid with the formula LuPO ₄ , colorless (white) crystals.

Getting

Heating a stoichiometric mixture of lutetium oxide and ammonium hydrogen phosphate :

{\mathsf {Lu_{2}O_{3}+2(NH_{4})_{2}HPO_{4}\ {\xrightarrow {950^{o}C}}\ 2LuPO_{4}+4NH_{3}+3H_{2}O}}

{\ displaystyle {\ mathsf {Lu_ {2} O_ {3} +2 (NH_ {4}) _ {2} HPO_ {4} \ {\ xrightarrow {950 ^ {o} C}} \ 2LuPO_ {4} + 4NH_ {3} + 3H_ {2} O}}}
