A chemical method to synthesize MgNb2O6 and PbMg1/3Nb3/2O3 is discussed. Rietveld analysis performed with program DBWS-9807a was used to study the crystal structure, and to characterize the microstructure of MgNb2O6 and PbMg1/3Nb3/2O3. Changes in the unit cell dimensions and the variations of crystallite size and microstrains, which occurred when Li was… CONTINUE READING
