The influence of batch time as well as the saturation temperature of stock solution on crystal size distribution has been examined. The results show that there is an optimal batch time, tc, for which the mean crystal size of MgSO4.7 H2O has a maximum. For MgSO4.7 H2O and H2C2O4.2 H2O, the mean crystal size of the product increased with increasing saturation temperature of the solution.
