Abstract
The invention relates to a method for dividing silicon blocks, including the following steps: providing a cuboidal silicon block, dividing the silicon block into at least two bars in a first dividing step, turning the bars in a turning step by 90° respectively around a rotational axis perpendicular to the longitudinal direction of the block and dividing the bars into silicon ingots in a second dividing step.

System for dividing silicon blocks comprising:
- a. a holding device for holding a silicon block to be divided,
- b. a first briquetting machine with a wire web, and
- c. a second briquetting machine with two partial wire webs, which respectively have several parallel cutting sections, wherein the cutting sections of the partial wire webs extend respectively perpendicular to each other.
Method for dividing silicon blocks comprising the following steps:
