“…In the present work a possible concentration of radioactive impurities in a surface layer of the ZnWO 4 crystal obtained by recrystallization was also checked. [21,22,23] in a platinum crucible 50 mm in diameter with 99.93% Pt purity level. The crystallization rate was 1.5 mm/h.…”

“…It is usually claimed that the facetting is harmful for crystal quality [41] and thus should be avoided by keeping thermal gradient above a critical value. However, recently large nearly perfect crystals of bismuth germanate have been grown with the fully facetted solidi¯cation front [6]. A numerical treatment of the partially facetted interface has been discussed recently in [59].…”

Abstract:Numerical simulation of industrial crystal growth is di¯cult due to its multidisciplinary nature and the complex geometry of the real-life growth equipment. An attempt is made to itemize physical phenomena dominant in the di¬erent methods for growth of bulk crystals from the melt and the vapor phase as well as to review corresponding numerical approaches. Academic research and industrial applications are compared. Development of a computational engine and a graphic user interface of the industry-oriented codes is discussed. A simulator for the entire growth process of bulk crystals by sublimation method is described.

Abstract. Numerical simulation of industrial crystal growth is difficult due to its multidisciplinary nature and complex geometry of real-life growth equipment. An attempt is made to itemize physical phenomena dominant in different methods for growth of bulk crystals from melt and from vapour phase and to review corresponding numerical approaches. Academic research and industrial applications are compared. Development of computational engine and graphic user interface of industryoriented codes is discussesd. In conclusion, a simulator for the entire growth process of bulk crystals by sublimation method is described.
