​Sapphire crystal growth method

Sapphire crystal growth method

The classification of crystal growth methods [1-4] is based on the phase state, initial composition and growth process conditions. Based on these factors, the growth methods can be distinguished into the following groups:

Crystals grow in the gas phase using a gas pressure gradient

Crystal Growth at Crystal-Solution Interface in Solution Using Concentration Gradients

Crystals use temperature gradients to grow in molten bodies

crystals grow in solid phase

The same single crystal can be grown by different methods. The classification with the type of phase transition (from gas phase, solution, melt or solid phase) is somewhat arbitrary, as the crystal formation process often goes through several phases. More detailed feature-based, The classification of creators etc. may seem confusing. For example, in the literature one may encounter the terms "active solvent" and "regional melting with a temperature gradient". Both terms refer to the same process: in In some articles he is the Tamman or Obreimov-Shubnikov method, and in others the Bridgman-Stockbarger process. This is due to the fact that these methods were used at different times to grow certain materials and subsequently generalized to other materials. Although the use of The classification of crystal growth methods for phase transformation forms is formal, and we will still use it.

Sapphire can be grown from gas, liquid and solid phases. A rich literature focused on methods to obtain sapphire from different media contains both theoretical and practical data on crystal growth. Our aim is to provide the reader with the means to select the most suitable method Logic. This logic is based on the physical-chemical fundamentals of the growth process and the properties of a particular method.
