Effect of precipitation conditions on the morphology of strontium molybdate agglomerates

Abstract : Preliminary experimental results about precipitation of strontium molybdate particles show that they have morphology as hierarchical agglomerates [A. Cameirao, R. David, F. Espitalier, F. Gruy, Multiple agglomeration in strontium molybdate precipitation, 16th ISIC, 2005, pp. 355-360]. The precipitation of strontium molybdate was studied and monitored in a batch reactor. The precipitation parameters, i.e. initial concentration of strontium molybdate. temperature and stirring rate, have an effect on the particles and agglomerates morphology. The shapes of the crystals were observed by SEM, and the PSD was measured at the end of precipitation by laser diffraction. The powders were also analysed by XRD, surface area (BET) and porosity measurements. Finally, a model of agglomeration was designed in order to predict the morphology of the observed agglomerates.
