TIEGEL FÜR EINE VORRICHTUNG ZUR HERSTELLUNG EINES KRISTALLINEN BLOCKES, UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

Crucible for a device for the fabrication of a block of crystalline material by controlled crystallisation has some lateral walls (8) and a bottom (7). The bottom of the crucible, parallel to an axis essentially perpendicular to the bottom, has some thermal transfer properties considerably greater than those of the lateral walls. The bottom of the crucible is transparent to infrared radiation whilst the lateral walls are opaque to infrared radiation. Independent claims are also included for: (a) a device for the fabrication of a block of crystalline material by controlled crystallisation incorporating this crucible; (b) the fabrication of a block of crystalline material by controlled crystallisation using this device.
