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.
