Solvothermal preparation of nano-sized CaWO4 particles

CaWO4 was prepared by solvothermal reaction of Na 2WO4.2H2O and calcium salts (CaCl 2.2H2O, Ca(NO3)2.4H2O and Ca(CH3COO)2) in solvent containing a variety of glycerol/water ratios at 160 °C for 6 h. By using XRD, SEM, TEM and ED, the products compose of nano-sized CaWO4 particles with scheelite stru...
