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.{{Cite journal |last1=Pan |first1=Sudip |last2=Ghara |first2=Manas |last3=Ghosh |first3=Sreyan |last4=Chattaraj |first4=Pratim K. |date=2016 |title=Noble gas bound beryllium chromate and beryllium hydrogen phosphate: a comparison with noble gas bound beryllium oxide |url=http://xlink.rsc.org/?DOI=C6RA20232B |journal=RSC Advances |language=en |volume=6 |issue=95 |pages=92786–92794 |doi=10.1039/C6RA20232B |bibcode=2016RSCAd...692786P |issn=2046-2069|url-access=subscription }} 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:{{Cite journal |last1=Bleyer |first1=B. |last2=Moormann |first2=A. |date=1912-06-11 |title=Über Berylliumchromate |url=https://onlinelibrary.wiley.com/doi/10.1002/zaac.19120760105 |journal=Zeitschrift für anorganische Chemie |language=en |volume=76 |issue=1 |pages=70–78 |doi=10.1002/zaac.19120760105}}
:Be(OH)2 + CrO3 → BeCrO4 + H2O
The reaction of potassium chromate and beryllium sulfate is claimed to produce beryllium hydroxide:{{Cite journal |last=Orlow |first=N.

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