Keywords:mineral , impurities, crystal

Crystals produced by crystallizing from hot water or magma come in various sizes, lengths, and thicknesses. As a factor that changes these, the presence of impurities that are not related to the components of the product can be considered. However, it is not known how impurities affect the crystallized minerals. In this study, NH4H2PO4 is crystallized with NaCl as an impurity.
