ABSTRACT:
Apparatus includes a crucible, a cover with an opening over the crucible, a pulling element for pulling monocrystal from melt in the crucible, and first and second heating elements. The first element is a substantially flat radiaent heat source below the crucible and the second element is a pot shaped, comprising a flat heat source above the melt and a cylindrical heat source about the crucible. A ring having holes therethrough is inserted in the crucible to quiet the melt, a filler funnel emptying material to be molten outside of the ring while the monocrystal is pulled from inside the ring.
