Experimental study on effects of factors on the reaction crystallization of silver chloride in rushton type reactor. The size and size distributions of the silver chloride crystals were observed to be markedly affected by the agitation speed of solution, and feeding rate, feeding mode and concentration of reactants. From experimental data it was inferred that in the reaction crystallization of silver chloride the supersaturation level of silver chloride and concentration of excess ions in the solution, and mass transfer rate around the crystals were implicitly interrelated with factors and directly affected on the crystal nucleation and grwoth processes. However, the morphology of the silver chloride crystal was not changed by factors.
