THE GROWER crystallization of refractory pseudo-single EUTECTIC

摘要

The invention relates to growing single crystals of high-melting and crystallization plants. Crystallisation system for growing high-melting eutectic pseudo-single comprising a crucible with a cooling medium, the primary heater, the sub-heater, a single crystal, single crystal moving device, characterized in that it additionally introduced second crucible, in which a crucible with a cooling medium and a transfer apparatus of the single crystal, single crystal seed Nb, placed in a crucible with a cooling medium, an insulator insulating the sub-heater with the cooling of the crucible medium polycrystal on the one hand coupled to the transfer apparatus of the single crystal, and on the other hand, - with a single crystal on the single crystal growing seed. In this polycrystal is a mixture of polycrystalline Nb + Nb ₃ Si.
