Beryllium vanadates

Beryllium Vanadate.—Berzelius (1831 3) in his researches on the vanadates obtained a yellow, neutral, difficultly soluble beryllium vanadate which was not studied and to which no formula was assigned. 

Obtained a yellow, neutral, dfficultly soluble, powdered beryllium vanadate. 

Beryllium Metavanadate, Be(V03)2.4H20.—Addition of solutions of beryllium salts to alkali vanadates gives rise to basic vanadates of indefinite composition. The pure salt is obtained by boiling beryllium hydroxide and vanadium pentoxide in water in the required proportions. The solution is filtered, concentrated to a syrup and poured into alcohol, whereupon isometric cubes, modified by an octahedron, are obtained. The larger crystals polarise light. Density, 2-273. One gram dissolves in a litre of water at 25° C.s...

Sodium Beryllium Silicate.— Hautefeuille and Perrey (1890 II and 1893 t) in manner analogous to their corresponding potassium compounds by fusing the constituents of a beryllium nephdene in excess of sodium vanadate, obtain crystals of a silicate varying between wide limits and which they concluded were rnixtures of simpler types.
