Abstract: On a melt (44) of crystallisable material a plate (16) is allowed to float which has a central passage (18) into which a preferably rotating seed crystal is lowered and then retracted, in order to generate an interface (24) between solid and liquid.

In order to avoid sticking and jamming, at least the inner surface of the passage (18) consists of a material which is not wettable by the melt (44). The stresses in the growing crystal can be minimised by the passage (18) being centred with respect to the axis of rotation of the mechanism (22) which rotates and raises the growing crystal. The plate (16) is preferably symmetric, and elongated fingers (28) project downwards from a support (30) fastened to the crystal raising and rotating mechanism (22) and are in contact with points on the perimeter of the plate (16) in order to align the plate (16) axially with the axis of rotation of the mechanism (22). <IMAGE>
