Crystal growth rules of mixture crystals KADP (potassium dihydrogen phosphate (KDP) and ammonium dihydrogen phosphate (ADP)) have been analyzed based on the solubility product principle. The heteroepitaxial layers have been obtained by immersing KDP (ADP) substrate into the ADP (KDP) saturated solution at 313 K. The micromorphology indicates that small growing points on different planes show the self‐similar property compared to the bulk crystal's morphology. The process of epitaxial growth depends on not only form the lattice match but also form crystallizing kinetics which is the main influencing factor. Moreover, it can infer from the micromorphology on the surface of the mixed crystal that the dissolving of substrates will form mixed solution on epitaxial surface. What's more, corrosion phenomenon gets more and more evident with increasing times of epitaxial growth and it will be harder to form transparent epitaxial layers due to the increasing tension of epitaxial layers.
