Beryllium chromate is a hypothetical inorganic compound, with the chemical formula of BeCrO₄. It is predicted to have a certain bonding ability with noble gases.^[1] Little evidence has been published supporting the existence of this material.

Claims

Beryllium chromate is claimed to be obtained from the reaction of beryllium hydroxide and chromium trioxide:^[2]

Be(OH)₂ + CrO₃ → BeCrO₄ + H₂O

The reaction of potassium chromate and beryllium sulfate is claimed to produce beryllium hydroxide:^[3]

BeSO₄ + 2K₂CrO₄ + H₂O → K₂Cr₂O₇ + K₂SO₄ + Be(OH)₂
