Abstract : This abstract discloses a furnace for growing large single crystals from materials having high melting temperature using the vertical solidification of melt method. The crucible containing the melt is encased in a muffle with vertically oriented heating rods arranged in a circular pattern around the outside of the muffle. The tops of the hearing rods are electrically connected to a continuous graphite ring, and the bottoms of equal numbers of rods are electrically connected to two semi-circular sections of graphite. The power feeds for the heating rods are vertically brought into the furnace from the bottom for electrical connection to the semi-circular sections of graphite.
