ABSTRACT:
A zig-zag picket graphite heater for use in high temperature furnaces of the type used for crystal growing, for example, utilizes a plurality of discrete graphite arcuate shell segments having vertically extending slots alternating from the upper and lower ends thereof. The edge pickets are adjacent slots which extend upwardly from the lower end of the segment and have extensions projecting below the other pickets so as to provide pads below the level of the slots. Graphite connectors span the adjacent pads of adjacent arcuate segments and certain of the connectors are also connected to electrical power supply terminals.
