Cyclic microwave-assisted synthesis and characterization of nano-crystalline alkaline earth metal tungstates

Nano-crystalline MWO4 (M = Ca, Sr and Ba) were successfully produced using cyclic microwave radiation in propylene glycol. XRD, TEM, SAED and EDX analyses revealed the presence of nano-crystalline MWO4 containing the corresponding alkaline earth metals, W and O. Their lattice parameters and crystall...
