Nickel(II) chromate (NiCrO4) is an acid-soluble compound, red-brown in color, with high tolerances for heat.

It and the ions that compose it have been linked to tumor formation and gene mutation, particularly to wildlife.

[3] If the pressure is too low or temperature too high but above 660 °C, then the nickel chromium spinel NiCr2O4 forms instead.

[3] Karin Brandt also claimed to make nickel chromate using a hydrothermal technique.

[3] The infrared spectrum of nickel chromate show two sets of absorption bands.
