Abstract

A series of tungstate scheelite structured MWO 4 (M=Ca, Sr, Pb and Ba) were synthesised using the sucrose solution evaporation method. Characterisation of these materials revealed that nanoparticles were formed, with the calcination temperature >400°C. The nanoparticle powders formed are crystalline and exist in its pure phase. It is found that the degree of crystalline products is low with the decrease in ionic radius (Ca
