20120141336 | DEVICE AND PROCESS FOR PRODUCING A BLOCK OF CRYSTALLINE MATERIAL - A temperature gradient is established in a crystallization crucible by means of a heat source and a cooling system. The cooling system comprises a heat exchanger and an adjustable additional heat source. The cooling system is preferably formed by an induction coil cooled by a coolant liquid circulating in the induction coil and by an electrically conductive induction susceptor positioned between the crucible and induction coil. The fabrication process comprises heating the crucible via the top and controlling heat extraction from the crucible downwards by means of the heat exchanger and by means of regulation of the adjustable additional heat source. | 06-07-2012 |
20100089310 | DEVICE AND METHOD FOR PRODUCING SELF-SUSTAINED PLATES OF SILICON OR OTHER CRYSTALLINE MATERIALS - The device for producing a sheet of crystalline material by directional solidification of a material in liquid phase composed of a crucible provided with a bottom, side walls and at least one horizontal outlet slot arranged on a bottom part of a side wall. On its external surface in immediate proximity to the slot, the crucible presents electromagnetic means for creating magnetic repulsion forces on the material in liquid phase, at least at the level of the slot. An alternating current with a frequency comprised between 10 kHz and 300 kHz flows through the electromagnetic means. To foster stirring of the material in liquid phase, a low frequency can be used in addition to the above frequencies. | 04-15-2010 |
