In particular the expediency of use of succinonitryl as crystal substance is proved. Equations of a thermal and concentration convection are adduced and analyzed. Distribution of temperature at taking into account the convection and without it, is investigated in the limited cylinder. The research technique of interaction and interference of the crystallization interface shape and the gravitational convection is offered. Distribution of temperature in the cylindrical ampoule moving from a heater to a cooler at crystallization on Bridgman method is investigated. The received theoretical results are illustrated on examples with the help of numerical simulation.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
