“…It is worth noting that in the homogeneous solid-liquid crystal growth process, the phenomenon that large amounts of small pyramids gradually evolved into a large pyramid will still show in (001) plane [8,18], but under this situation, all the surfaces in crystal grown faster and would evolve into a larger size in (001) plane on each piece of monocrystal compared to the heteroepitaxial growth process. This proved the statement that these growing points may be originated from the defects produced by partial corrosions between solvent and the substrate which was also appropriate for the situation of homogeneous solid-liquid crystal growth.…”

“…KDP and ADP have been extensively studied for many years due to their important applications such as nonlinear optics (NLO), quantum electronics (QE) [6][7][8], and especially, inertial confinement fusion (ICF) [6]. In the few past decades, an increasing number of experiments have been devoted to seek an efficient way of promote the crystal quality and obtain bulk crystal.…”

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.

“…One opinion argued that the better hydrodynamic conditions thus higher supersaturation near edges induced thin surface layers forming from the edges, but experimental results denied it . Some scholars thought the thin surface layer is steps generating from edges, yet they did not explain why the steps can spread into solution directly. In the very beginning of our study on this question, we investigated and pondered the effects of dynamic conditions such as supersaturation, temperature, flow, gravity, and so forth, it is found that none of these factors can fundamentally explain why the steps can spread into solution directly.…”

The thin surface layer growth during the regeneration of incomplete potassium dihydrogen phosphate crystal is more perplexing than the ordinary layer‐by‐layer growth. In a previous paper, the driving force of the thin surface layer growth was discussed; the present paper focuses on the regeneration process and final regeneration morphology. Based on the analysis of thin surface layer area per unit repaired volume, it is found that convex polyhedron is more advantageous than concave polyhedron. It is also found that the general morphology of repaired incomplete crystal is convex polyhedron of minimum volume covered by singular surfaces. The most important thing is, numbers of regeneration details suggest that the incomplete crystal achieves the self‐repairing by morphology prejudging.

Numerical simulations are performed to study the rapid growth of potassium dihydrogen phosphate crystals with a designed stirring paddle. The paddle is expected to produce a downward flow and enhance mass transfer near the crystal surface. The effects of rotation rate and crystal size on downward flow speed are investigated. As the rotation rate and crystal size increase, the downward flow speed increases linearly. The mass transport in the turbulent boundary layer is analyzed, and the surface supersaturation is calculated theoretically. The solute supply can be guaranteed by controlling the rotation speed of the stirring paddle during crystal growth.
