'''磷酸镍'''是一种[[无机化合物]]，化学式为Ni<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>。

==制备及反应==
磷酸镍的八水合物可由[[镍化合物|镍盐]]和[[磷酸氢二钠]]在溶液中反应，沉淀得到：
: <math>\mathsf{3NiCl_2 + 2Na_2HPO_4 + 8H_2O \ \xrightarrow{}\ Ni_3(PO_4)_2\cdot 8H_2O\downarrow + 4NaCl + 2HCl }</math>
根据反应物[[化学计量比]]和温度的不同，也会生成NH<sub>4</sub>NiPO<sub>4</sub>·nH<sub>2</sub>O（n=1或6）。<ref name=ito>Ito, Seisiro; Hasegawa, Masaki; Kuwahara, Tosihide.
