Is the quartz crucible drawn by monocrystalline silicon disposable?
One must, one pot, 3000 pieces! Or made in China?
Yes, once a quartz crucible has been used, it will crack or break even after high temperature and cooling. And the single crystal drawing requires a high-purity quartz crucible.
The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable
