Beryllium Chromate, BeCrO₄

Glassmann claimed to have obtained the normal chromate, BeCrO₄.H₂O, in reddish-yellow, monoclinic crystals by dissolving the carbonate in concentrated chromic acid, and the yellow basic chromate, BeCrO₄.6Be(OH)₂, by decomposing this with water. Bleyer and Moorman failed to obtain them, though solutions were obtained containing Be and Cr in the ratio 1:1. They state that 15BeO.CrO₃.12H₂O is precipitated by potassium chromate from solutions of beryllium chloride, however the proportions of these are varied.
