磷酸镍是一种无机化合物,化学式为Ni3(PO4)2。
制备及反应
磷酸镍的八水合物可由镍盐和磷酸氢二钠在溶液中反应,沉淀得到:
![{\displaystyle {\mathsf {3NiCl_{2}+2Na_{2}HPO_{4}+8H_{2}O\ {\xrightarrow {}}\ Ni_{3}(PO_{4})_{2}\cdot 8H_{2}O\downarrow +4NaCl+2HCl}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/d47bd6b332b1052408f66a8f552d8e71ce64a3a4)
根据反应物化学计量比和温度的不同,也会生成NH4NiPO4·nH2O(n=1或6)。[2]它热分解得到Ni2P2O7。[2]它可以被氢气在高温下还原为磷化二镍。[3]
