1. A method for manufacturing silicon blocks (4) comprising the following steps:
a. providing an apparatus (24) for solidifying a silicon melt, the apparatus comprising
i. a crucible (1),ii. a temperature controller (23) connected to at least one heating device (26, 27), andii. a device (12) for removing liquid silicon from a crucible, the device comprising at least one block (13) of a refractory with a capillary structure, b. providing a silicon melt within the crucible (1), c. partly solidifying the silicon melt, d. bringing the at least one block (13) of the refractory in contact with liquid silicon on top of the solidified silicon in a contacting step, e. taking up at least a predetermined amount of the liquid silicon with help of the at least one block (13) in a taking up step, and f. bringing the at least one block (13) of the refractory out of contact with the silicon in the crucible (1) in a removal step. |
