Shell for reinforcing a quartz crucible

The present shell (2) for reinforcing a quartz crucible is constructed from a carbon fibre which is compacted (densified, compressed) to 10 to 150% with lustrous carbon and has through holes (14), the ratio between the total area of the cross-section of these through holes and the area of the outer...
