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
