Characterization of micro-crystalline lead tungstate with different morphologies produced by the sonochemical process

Characterization of micro-crystalline lead tungstate with different morphologies produced by the sonochemical process

Micro-crystalline PbWO4 was sonochemically produced using Pb(CH3COO)2 • 3H2O and Na 2WO4 • 2H2O in aqueous solutions with and without anionic surfactant (sodium dodecyl sulphate or sodium lauryl sulphate). The product morphologies were influenced by the pH values and the surfactant. Micro-crystallin...
