This article summarizes the theory and practice of the growth of single crystals. Today, the growth of crystals having dimensions of some hundred millimeters in diameter and weights over 200 kg under extreme pure conditions is well-matured in industrial scale. The major user of the crystals is the electronics industry.

Growth of crystals demands theoretical knowledge of thermodynamics, kinetics, and transport processes. In practice, some general aspects have to be considered, including choice of raw materials, conditions, methods, and characterization. The industrial and laboratory techniques of crystal growth are discussed. Economical aspects dominate the developments in the future, that is, growing of larger crystals at higher quality to raise yields and device performance. Furthermore, the demand for tighter specifications and increasing range of materials and uses will require more sophisticated methods and an extensive use of automation.
