Strontium metavanadate

Basic Strontium Metavanadate, 8Sr0.2V205.2Ha0 or Sr0.2Sr(V03)2. 2H20, has also been prepared.10... 

Calcium Metavanadate, Ca(V03)2.3H20, gives rise to bright yellow needles when a solution of ammonium metavanadate is boiled with calcium chloride solution and precipitated with alcohol.6 The tetra-hydrate, Ca(V03)2.4H20, is prepared by allowing a mixture of potassium metavanadate and calcium chloride to evaporate for several days.7 Anhydrous calcium metavanadate is a white, porous substance, which is unaffected by strong heating, but is readily decomposed by acids to yield vanadium pentoxide.8 It is much more soluble in water than strontium metavanadate. 

Strontium Metavanadate, Sr(V03)ss.4H20, is obtained as colourless, monoclinic prisms by the action of strontium chloride on potassium metavanadate. It is only sparingly soluble in water and undergoes dehydration at 280° C.14...
