The doctrine of crystal growth is a much less harmonious and developed branch of crystal science than geometric crystallography, crystallophysics and crystal chemistry. Modern reviews show how heterogeneous and often contradictory is the theoretical and experimental material that makes up its content1). Nevertheless, the role of this area of ​ ​ knowledge is very great. It is based on the artificial cultivation of technical single crystals and the solution of numerous problems of physics, chemistry and physical chemistry related to the formation of a crystalline structure.
