Abstract (en)

[origin: WO2008132323A2] The invention relates to a device for making a plate (8) of a crystalline material by the directed crystallisation of a liquid-phase material (5), that comprises at least one crucible (1) with a bottom (2), side walls (3) and at least one horizontal outlet slot (4) provided on a lower portion of a side wall (3). The crucible (1) comprises, on its outer surface and in the immediate vicinity of the slot (4), electromagnetic means (6) for generating, at least at the slot (4), magnetic repulsion forces on the liquid-phase material (5). An alternating current with a frequency between 10kHz and 300kHz flows through the electromagnetic means (6). In order to promote the agitation of the liquid-phase material (5), a low frequency can be superimposed to the former.
