Abstract
In this paper, particles of calcium tungstate as a model compound were prepared by a reverse micelle’s method. The morphology of particles was tuned from rod to spindle-like and spherical by altering the temperature and concentration of reactants. A volume per single particle and a total number of particles were calculated to explain quantitatively the mechanism of influence of reaction conditions on the process. It was found that the reactant concentration had no effect on the number of particles. With increasing temperature or reaction time, the number of particles decreased, whereas the particle volume increased. The bulk water in the micelles seemed actually affect the size of particles.
