'''钨酸镍'''是一种[[无机化合物]]，[[化学式]]为NiWO<sub>4</sub>。它是黄色调的固体，其具体颜色和合成方法或处理方法有关。<ref name=YL /><ref>Yunxia Huang. Amorphous NiWO4 Nanospheres with High-Conductivity and -Capacitive Performance for Supercapacitors. J. Phys. Chem. C 2019, 123, 50, 30067–30076. {{doi|10.1021/acs.jpcc.9b08448}}.</ref>

==制备及性质==
钨酸镍可由[[硝酸镍]]和[[钨酸钠]]反应得到：
:<math>\mathsf{ Ni(NO_3)_2 + Na_2WO_4 \ \xrightarrow{}\ NiWO_4\downarrow + 2NaNO_3 }</math>

从溶液中沉淀出的钨酸镍为绿色固体，它加热失水后逐渐变黄。<ref>Ana G.C. Sales. Heat treatment influence on structural and optical properties of NiWO4 crystals.
