A device for the growth of the single crystals on the basis of the molten mass by using the supply of make-up with load flour

摘要

P the device comprises means of drawing the single crystal from the melting and mass 16 in a crucible 5 constituted by two reservoirs 6 and 7 mounted coaxially and delimiting between them an annular cavity serving to receive the load. The internal reservoir 6 projects downwards with respect to the external reservoir 7 and, in this projecting part, is the molten mass. / p & & p & in the lateral wall of the reservoir inside and at the level of the bottom of the external reservoir, are made of the outflow orifices of the molten mass 16 of the annular cavity to the internal reservoir 6. At - bottom of the reservoirs are mounted inside and outside of the heaters autonomous 11 and 12. This device can be used in particular to the growth of crystals, as well as a single optical semiconductor - conductors. / p
