Preparation and characterization of nanocrystalline SrWO4 using cyclic microwave radiation

Nanocrystalline SrWO4was successfully prepared using SrCl2and Na2WO4in ethylene glycol at different pH values, microwave powers and prolonged times. The phase was detected using XRD and SAED. TEM, HRTEM, SEM and particle size distribution revealed the presence of nano-sized crystals with their cryst...
