Abstract: The title metavanadates were prepared in argon atmosphere using vanadium sesquioxide as a starting material. The optimum preparation conditions are:V2O3: La2O3=1:0. 99,pass argon gas for 45 min at 0.5L/min,heat to 1300℃ for 5h.XRD analysis indicated the products were monophase.

Key words: lathanutm metavanadate, neodymium metavanadate, vanadium sesquioxide, preparation
