  • Apparatus and method of growing and discharging single crystals
    Patent number: 4485072
    Abstract: Single crystals are grown from a melt in a frame-mounted furnace housing consisting of a stationary top furnace member and a movable base furnace member adapted to be butt-joined to the top one, and a vertically reciprocatable crystal-pull rod with a seed crystal holder extending into the top furnace member. A crucible with a heater is arranged in the base member. The base member is movable from beneath the top furnace member to permit the pull rod and the grown crystal to be lowered for removal of the crystal without lateral movement of the pull rod and/or crystal frame. A heat insulated discharge vessel is provided for receiving and transporting the removed crystal.
