鉻酸鎳是一種無機化合物，化學式為NiCrO₄，是可溶於酸的紅褐色固體，對熱穩定。該化合物可能會引起腫瘤或基因突變，對野生動物尤為突出。^[3]

製備[編輯]

鉻酸鎳可由三氧化二鉻和氧化鎳的混合物在700 °C至800°C於1000個氧壓下灼燒得到，若在535°C和7.3巴的氧氣中反應，則需要數天。^[4]如果壓力太低但溫度高於660°C，則會產生鎳鉻尖晶石NiCr₂O₄（亞鉻酸鎳）。^[4]

Karin Brandt也通過水熱反應製備了鉻酸鎳。^[5]^[6]用CrO2−
4沉澱Ni²⁺，可以得到棕色的水合物。^[7]

性質[編輯]

鉻酸鎳的結構和釩酸鉻（CrVO₄）相同，它屬正交晶系，晶胞參數為a=5.482 Å，b=8.237 Å，c=6.147 Å。^[6]^[8]

鉻酸鎳在低氧壓下於600°C分解：^[4]

4 NiCrO₄ → 2 NiCr₂O₄ + 2 NiO + 3 O₂↑
