In the first part of the presentation, we report on a large-scale synthesis of single crystalline LiNbO3 nanowires in the diameter range of 300-400 nm, containing some nanoparticle impurities, using a modified molten salt procedure. In the second part of the talk, we report on the synthesis of SRO submicron-sized particles via a molten-salt method. We have accomplished this by systematically probing experimental parameters such as precursors, type of salt, annealing time, annealing temperature, surfactant, cooling rate, and reaction atmosphere in an effort to predictably control the resulting size, shape, and morphology of the SRO product particles. Apart from the choice of molten salt which primarily controls chemical composition of SRO, we have determined that the most important experimental parameter for shape and aggregation control is the surfactant, because of a combination of its hydrophobic and hydrophilic characteristics.
