铬酸镍是一种无机化合物，化学式为NiCrO₄，是可溶于酸的红褐色固体，对热稳定。该化合物可能会引起肿瘤或基因突变，对野生动物尤为突出。^[3]

制备

铬酸镍可由三氧化二铬和氧化镍的混合物在700 °C至800°C于1000个氧压下灼烧得到，若在535°C和7.3巴的氧气中反应，则需要数天。^[4]如果压力太低但温度高于660°C，则会产生镍铬尖晶石NiCr₂O₄（亚铬酸镍）。^[4]

Karin Brandt也通过水热反应制备了铬酸镍。^[5]^[6]用CrO2−
4沉淀Ni²⁺，可以得到棕色的水合物。^[7]

性质

铬酸镍的结构和钒酸铬（CrVO₄）相同，它属正交晶系，晶胞参数为a=5.482 Å，b=8.237 Å，c=6.147 Å。^[6]^[8]

铬酸镍在低氧压下于600°C分解：^[4]

4 NiCrO₄ → 2 NiCr₂O₄ + 2 NiO + 3 O₂↑
