Barium molybdate and barium tungstate nanocrystals synthesized by a cyclic microwave irradiation
BaMoO4 and BaWO4 nanocrystals were synthesized from Ba(NO3)2 and Na2MeO4 (Me=Mo and W) solutions using 50% of 600 W microwave irradiation for 20 min. The products were characterized using X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), transmission electr...
